Automated floating tag creation

[rartych]

Problem description
v0 tag is used to reference the latest released version of reusable workflows.
Many projects automate this.

Possible evolution
The workflow like this can automatically update the v0 tag:

name: Update floating tags
on:
  push:
    tags:
      - 'v[0-9]+.[0-9]+.[0-9]+'

jobs:
  update-major-tag:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      
      - name: Update major version tag
        run: |
          TAG=${GITHUB_REF#refs/tags/}
          MAJOR=$(echo $TAG | cut -d. -f1)  # Extract v0 from v0.1.5
          
          git config user.name github-actions
          git config user.email github-actions@github.com
          git tag -f $MAJOR
          git push origin $MAJOR --force
