Cleanup public actions API

[trueberryless]

Changes

• Refactor public API of actions to reduce what is exported

  I think I missed a lot of refactorings needed. I just wanted to get the ball rolling and get some feedback on what I am doing right and wrong in this codebase. I think if I understand what to do once, I could apply it better to all necessary refactorings. Feel free to let me know if explaining the changes would take more time than it’s worth. I’m happy for you to handle them if that’s easier, and I can pick up something else afterward — no worries at all. I’d just be really happy to start contributing and become more helpful over time.

• Cleanup additional internals regarding actions

• Closes Cleanup actions public API #14608

Testing

I did not change any tests, as I think that these refactorings do not need new tests. Please let me know if I should add tests and if so, in which file(s)!
Unfortunately, I was unable to run tests locally.

Docs

No docs changed, this PR is intended to just refactor internal exports and remove public access to some types.
The docs were already adapted in withastro/docs#12596

Todo

• Write a proper changeset with breaking changes once I understand what I actually need to do 😅

First of all, the PR should be against the next branch!
