feat: add ADDITIONAL_OPTIONS for gh action

[eifinger]

Add ADDITIONAL_OPTIONS as an additional command for the github action.

Using it with --noop on PRs as shown below allows to verify that new configurations or versions will run successfully on the main branch:

name: Semantic Release

on:
  push:
    branches:
      - master
  pull_request:
    branches:
      - master

jobs:
  noop-release:
    if: github.ref != 'refs/heads/master'
    runs-on: ubuntu-latest

    steps:
    - uses: actions/checkout@v2
      with:
        fetch-depth: 0

    - name: Python Semantic Release Test
      uses: relekang/python-semantic-release@master
      with:
        github_token: ${{ secrets.GITHUB_TOKEN }}
        repository_username: __token__
        repository_password: ${{ secrets.PYPI_TOKEN }}
        additional_options: --noop
  release:
    if: github.ref == 'refs/heads/master'
    runs-on: ubuntu-latest

    steps:
    - uses: actions/checkout@v2
      with:
        fetch-depth: 0

    - name: Python Semantic Release
      uses: relekang/python-semantic-release@master
      with:
        github_token: ${{ secrets.GITHUB_TOKEN }}
        repository_username: __token__
        repository_password: ${{ secrets.PYPI_TOKEN }}

It looks like you committed as the GitHub Actions account - do you want to fix this before merging?

[eifinger]

Thank you! Was overwritten when I tested the action.

This seems to be causing an error when the new option isn't used:

Yes I saw that as well and opened a fix PR: #479
