* Combine changes for Polkadot and Substrate
* Change sanitised_git_logs in `lib.sh` to drop `*`s at the start
* Only look for priorities of medium or above (presence of one or more
  C1 label is enforeced by check-labels anyway, saves us some API calls)

* Ensure priorities >C1-low aren't labelled B0-silent

labels. If labelled, will be included in the changelog, otherwise will
silently be left out.

* CI: make lib.sh /bin/sh-compatible

* lib.sh: fix newline chars sometimes breaking has_label()

* CI: make lib.sh /bin/sh-compatible

* ci: backport runtime version checks from v0.6 branch

* Fix gitlab release drafting script

Don't scan commit body for PR-like commit messages. Fix warnings from linter,
and take object URL for signing verification from /git/ref/tags rather than hard-coding

* Temporarily Disable GPG verification in pending...

...release alerts. GPG verification of objects is also done before creating the
draft release so this isn't as bad as it sounds

draft release so this isn't as bad as it sounds

* Remove accidental GH token leakage 😅

* Add publish_draft_release.sh

This new CI script will generate a list of differences between
this tagged version and the previous tagged version (including
substrate changes), and create a draft release on Github. Once
this is done, the draft release will be posted in Matrix (the
channel is determined by a Gitlab CI environment variable).
