Sorry, I pushed the merge button before the audit of the PR, this
reverts the commit for `stable2503` branch

For master branch seee:
https://github.com/paritytech/polkadot-sdk/pull/7615

This PR contains a tiny fix for the release branch-off pipeline, so that
node version bump works again.

Closes: #7291 

## Description

*Removes obsolete relayer CLI args from bridges and resolves following
issue: (https://github.com/paritytech/polkadot-sdk/issues/7291)*

One more attempt to fix the link-checker job.

This time we exclude polymesh which is reachable but not via lychee.
Also exclude rust strings that contain "{}" or "{:?}".

This PR implements `DecodeWithMemTracking` for the types in the frame
pallets

The PR is verbose, but it's very simple. `DecodeWithMemTracking` is
simply derived for most of the types. There are only 3 exceptions which
are isolated into 2 separate commits.

PR adds a resuable workflow that prevents CI to run on draft PRs. To run
CI on draft a new label is introduced: `A5-run-CI`. To run the CI the
label should be added and en empty commit should be pushed.

Fix issue where setting the `remote_fees` field of `InitiateTransfer` to
`None` could lead to unintended bypassing of fees in certain conditions.

Changes made to fix this:
- `remote_fees: None` now results in the `UnpaidExecution` instruction
being appended *after* the origin altering instruction, be it
`AliasOrigin` or `ClearOrigin`. This means `preserve_origin: true` must
be set if you want to have any chance of not paying for fees.
- The `AliasOrigin` instruction is not appended if the executor is
called with the root location (`Here`) since it would alias to itself.
Although this self-aliasing could be done, it needs the ecosystem to add
a new aliasing instruction, so we just skip it.
- Tweaked the `AllowExplicitUnpaidExecutionFrom` barrier to allow
receiving assets (via teleport or reserve asset transfer) and altering
the origin before actually using `UnpaidExecution`. This is to allow
unpaid teleports to work with `InitiateTransfer`.
- For this, the barrier now executes origin altering instructions and
keeps track of the modified origin. It then checks if this final origin
has enough permissions to not pay for fees. In order to follow the
`AliasOrigin` instruction it now takes a new generic `Aliasers` that
should be set to the XCM config item of the same name. This new generic
has a default value of `()`, effectively disallowing the use of
`AliasOrigin`.

Add a new extrinsic `dispatch_as_fallible`.

It's almost the same as [`Pallet::dispatch_as`] but forwards any error
of the inner call.

Closes #219.

And add more unit tests to cover `dispatch_as` and
`dispatch_as_fallible`.

Some prdoc are invalid, `prdoc check` is failing for them. This also
broke usage of parity-publish.

This PR fixes the invalid prdoc, and add a ci job to check the prdoc are
valid. I don't think the check is unstable considering it is a simple
yaml check, so I put the job as required.

Recreation of https://github.com/paritytech/polkadot-sdk/pull/7357 on
top of master. The old PR messes up the git history too much so I am
recreating it from scratch.

This PR is work in progress. It's purpose is to commit initial structure
of `pallet-staking-ah-client` and `pallet-staking-rc-client` to master.
The changes will be polished by a follow up PRs which will be
backported.

Related issues: https://github.com/paritytech/polkadot-sdk/issues/6167
and https://github.com/paritytech/polkadot-sdk/issues/6166

This PR introduces the initial structure for `pallet-ah-client` and
`pallet-rc-client`. These pallets will reside on the relay chain and
AssetHub, respectively, and will manage the interaction between
`pallet-session` on the relay chain and `pallet-staking` on AssetHub.

Both pallets are experimental and not intended for production use.

TODOs:
- [ ] Probably handle
https://github.com/paritytech/polkadot-sdk/issues/6344 here.
