[citest skip] Add changelog_to_tag.yml to .github/workflows

Description:
When a new changelog section is added to CHANGELOG.md and pushed,
changelog_to_tag.yml is triggered, which generates a new tag and
a new release.

Example of CHANGELOG.md changes:
  [9.9.9] - 2022-12-31
  --------------------

  ### New features

  - New feature A

  ### Bug fixes

  - Bug fix B

Using this example, when the commit on CHANGELOG.md is pushed, a
new tag "9.9.9" is added and Version 9.9.9 is released in github.
If tag "9.9.9" already exists, the CHANGELOG.md push fails.
