`minor_version_release` requires admin to merge version bump

[ZanSara]

Describe the bug Currently, the release process includes running the minor_version_release workflow: https://github.com/deepset-ai/haystack/actions/workflows/minor_version_release.yml However, this workflow produces a PR that, due to some unskippable required CI workflows, is impossible to merge for non-admins.

Expected behavior It should be possible to merge the resulting PR. As an alternative, we can go back recommending the release manager to perform those steps manually.
