[CD] Add Listening workflows for website publishing.

[ProjectSynchro]

This enables automatic publishing of the website, as well as the lua documentation.

Other PRs will require a personal access token, passed in as the secret name WEBSITE_ACCESS_TOKEN.
This should have workflow permissions to trigger workflows.

This should be merged before both naev/naev#1335 and naev/naev-website#5

If I understand correctly, this listens on other repos and when there are changes tries to update itself right?

Speaking of which, how to generate the repo key? This is not a personal token but a deploy key or webhook?

This is exactly right, the other repositories send a trigger via the REST API to this repository, which will run certain steps depending on what the trigger name is. (Think that manual-nightly script thingy)

I think I misworded my initial message in this thread, I meant to say: you will need to create and upload a personal access token as a secret, as you'd be sending a trigger for this workflow remotely. So long as that token has 'workflow' permissions it should work. The jobs on the other repositories would trigger this as 'you' (or another service account would do as well.. so long as it has access) and then this workflow would take care of committing changes and pushing them.

Have to figure out the token thing still, but looks good, thanks!
