Turning c-ts-mode.el, go-ts-mode.el, csharp-ts-mode.el etc into :core packages?

[Yuan Fu]

What are the implications of turning something into a :core package? I can’t 
find much description of it. If my understanding of it is correct, I think it 
would be beneficial to make new tree-sitter modes into :core packages. Right 
now they are pretty bare-bones, and haven’t been “battle-tested”. Making them 
core packages would allow us gradually improve them and fix errors that come 
up. Those files I mentioned in the subject are new files, if that matters. But 
I don’t know if there are any downsides of turning something into a :core 
package.

The new tree-sitter related files we have are:
- c-ts-mode.el
- java-ts-mode.el
- rust-ts-mode.el
- go-ts-mode.el
- dockerfile-ts-mode.el
- cmake-ts-mode.el
- yaml-ts-mode.el
- typescript-ts-mode.el
- ruby-ts-mode.el
- toml-ts-mode.el

And we have a few “combined” files:
- python.el (already a :core package)
- js.el
- sh-script.el
