Update the template synchronization script (#5022)

There are slight changes required, after
https://github.com/paritytech/polkadot-sdk/pull/4716.

In order to follow the convention in the templates, we need to specify
the internal template dependencies (runtime and a pallet) in the main
`Cargo.toml`.

Additionally, there are now dependencies with `path` in the main
`Cargo.toml`, so we add a step with `psvm` to change those references to
crate versions.
