Add GitHub Action workflow to publish setup-php to NPM and GitHub Packages

[shivammathur]

Currently, after every release, I manually update the NPM package. A workflow can be added to do this when a new release tag is created. Also the same can start publishing to GitHub Packages as well.

Hey, is this something I can take a stab at? Any specific way/approach you have in mind? Using something like semantic-release...?

[shivammathur]

@aneeshrelan Yes, feel free to submit a PR.

With this, we just want to automate publishing to NPM and GH Packages, not complete releases. So semantic-release is not required.

If you go through this guide by GitHub, it has the workflow for publishing to NPM and GH Packages. You just have to implement it in setup-php.

If you have any questions about anything in the workflow, you can use this GitHub Actions reference or ask me here.

Thanks for the help @shivammathur. I'll have something ready soon

[aneeshrelan]

@shivammathur Do you want to run some other jobs before releasing? Like lint and/or tests or a simple publish is sufficient?

[shivammathur]

For every commit eslint is run in the node workflow, so in this workflow we can just publish.
