feat!: better defaults for copy_directories + only add existing ones

[mrcjkb]

BREAKING CHANGE: This could result in new directories being added to packages that did not set the copy_directories input.

I've noticed that :help runtimepath does not include some common plugin directories like autoload, queries, ...

Since adding new defaults is technically a breaking change, we should probably as for feedback on which directories to add in some Neovim groups.

Update: Nevermind. autoload is there. It's just queries, which is a directory used by nvim-treesitter.
This PR should be ready now.

my experience with CI is that the more code you move to the script and the less you expose in the CI-only part is better. It makes troubleshooting easier. In the long run, I think it's better to implement the default directly in luarocks-tag-release.lua.

As you mentioned you wanted the action to remain generic, maybe instead we could have an input: "neovimplugin" (autodetected according to label even) that would change some settings:

• add "neovim" label
• add these folders to copy_directories

I see your point about troubleshooting.
But I'm not sure how I feel about a separate input or logic that causes directories to be added on top of the copy_directories input based on some condition. That sounds to me like it could increase complexity (both internally and from a UX viewpoint). I might be wrong though...

Another option would be to add the default plugin directories if the copy_directories input has the value {{ neovim.plugin.dirs }} (which we could set by default).

I'll put some more thought into it in the next few days.

I have updated this with the {{ neovim.plugin.dirs }} approach.
