WIP: Run try-runtime hooks in CI

[ggwpez]

Depends on https://github.com/paritytech/substrate/pull/13045 so we can run it in a timely manner.

Currently the pre_ and post_upgrade hooks do not run because of new CLI behavious. Enabling the checks again with --checks.

TODO:

• [ ] Verify CI output
• [ ] Remove old migrations, if needed
• [ ] Remove runtime-migration label after merge

What's the status here?

What's the status here?

That we probably need to add a new label for the release engies to use, since we cannot expect the try-runtime of master to work, in case Polkadot is not yet on the latest release.

We can add a way to demote the error of an pre_upgrade to a warning, which could improve development speed since we dont always need to re-build and re-try after removing each old migration. Then we either the warning for master and the error on release, or just warning everywhere :shrug:
Having old migrations is not an "error" anyway. @kianenigma
