Consider renaming actions/checks to actions/basic-checks and converting actions/checks to composite action?

I was pondering that it might be worth renaming `SymbiFlow/actions/checks` to something like `SymbiFlow/actions/basic-checks` or `SymbiFlow/actions/custom-checks` and then converting `SymbiFlow/actions/checks` into a composite action which does a whole bunch of "good to have enabled" type checking.

Things like;
* Automatic spell checking of code - https://github.com/codespell-project/actions-codespell
* Other things I can't think of at the moment.

The primary issue is that a composite action can't run multiple checking jobs in parallel....
