feat: add GitHub workflow to force conventional commits formatted PR title

[toddeTV]

For PR names & also when names are changes right before the merge -> so to say the new commit msg that will go to main.

Something like the following, but better & not for semver:

name: PR Title Semver Check

on:
  pull_request:
    types: [opened, edited, synchronize]

jobs:
  check-semver-title:
    runs-on: ubuntu-latest
    steps:
      - name: Checkout repository
        uses: actions/checkout@v4

      - name: Get PR title
        id: pr_title
        run: |
          PR_TITLE=$(curl -s -H "Authorization: token ${{ secrets.GITHUB_TOKEN }}" \
          "https://api.github.com/repos/${{ github.repository }}/pulls/${{ github.event.pull_request.number }}" \
          | jq -r .title)
          echo "PR_TITLE=$PR_TITLE" >> $GITHUB_ENV

      - name: Check if PR title matches Semver pattern
        run: |
          echo "PR Title: $PR_TITLE"
          if [[ ! "$PR_TITLE" =~ ^(v[0-9]+\.[0-9]+\.[0-9]+|[0-9]+\.[0-9]+\.[0-9]+)$ ]]; then
            echo "Error: PR title does not follow Semver format."
            exit 1
          fi
