Tom Foster ae184aff3d fix(actions): correct invalid shell syntax across all actions

Fixed shell: python3 (invalid) to shell: python (valid) in:
- check-nodejs-versions: Also added visible output for debugging
- check-deadsnakes-versions: Fixed shell syntax
- create-pull-request: Fixed shell syntax

The previous commit 7a380c1 introduced invalid shell syntax which
caused actions to silently fail, resulting in empty NODE_VERSIONS
build args and broken Docker images without Node.js.

This fixes the root cause of the "node: executable file not found"
error during workflow runs.

Check Deadsnakes Python Versions Action

A Forgejo/GitHub Actions composite action that queries the deadsnakes PPA to find Python versions available across specified Ubuntu releases.

Usage

- name: Check available Python versions
  id: python-check
  uses: ./.forgejo/actions/check-deadsnakes-python
  with:
    ubuntu-versions: "22.04 24.04 25.04"

- name: Display results
  run: |
    echo "Common Python versions: ${{ steps.python-check.outputs.python-versions }}"

Inputs

Input	Description	Default	Required	Example
`ubuntu-versions`	Space-separated list of Ubuntu versions	-	Yes	`22.04 24.04 25.04`
`limit`	Maximum number of Python versions to return (newest are selected)	`3`	No	`2`

Outputs

Output	Description	Example
`python-versions`	Space-separated list of Python versions available across ALL specified Ubuntu releases	`3.9 3.11 3.13` (with limit=3)

How it works

Queries the Launchpad API for the deadsnakes PPA description
Parses the "Supported Ubuntu and Python Versions" section
Finds the intersection of Python versions across all specified Ubuntu releases
Applies the limit (if set) to return only the newest versions
Returns only versions available in ALL specified releases

Example workflow usage

name: Build with dynamic Python versions
on: [push]

jobs:
  check-python:
    runs-on: ubuntu-latest
    outputs:
      python-versions: ${{ steps.check.outputs.python-versions }}
    steps:
      - uses: actions/checkout@v4
      - id: check
        uses: ./.forgejo/actions/check-deadsnakes-python
        with:
          ubuntu-versions: "22.04 24.04"

  build:
    needs: check-python
    runs-on: ubuntu-latest
    strategy:
      matrix:
        # Convert space-separated string to array
        python: ${{ fromJSON(format('[{0}]', replace(needs.check-python.outputs.python-versions, ' ', ','))) }}
    steps:
      - name: Build with Python ${{ matrix.python }}
        run: echo "Building with Python ${{ matrix.python }}"

Notes

Ubuntu versions not supported by deadsnakes (e.g., 25.04) will be noted in the exclusions output
The action only returns Python versions available via deadsnakes, not native Ubuntu packages
Python versions are returned in sorted order (e.g., 3.7 before 3.11)
