How do you access the clipboard with this setting? Do you rebind Ctrl-V back to paste in insert mode?

I think I'd prefer the default register to be different from the clipboard register. However, that might be more work to implement.

Please feel free to merge this PR without resolving these, since I'm asking for additional features that can be worked on by people who need them in separate PRs.

@ilyagr Yep, similarly to VSCodeVim and others, you'd use the built-in commands to manipulate the clipboard. Further settings to assign another register to the clipboard might be interesting, though.

Even if we only support null and "dquote" (the default) in this PR, it might be interesting to change "dance.useSystemClipboard": boolean to "dance.clipboardRegister": "<register>" | null for better support of such future changes.

Thanks for the feedback, I've adjusted the setting to be a dropdown so the user can select their own clipboard register.
The current options are ", null, and A-Z, but I'm happy to change those as you see fit.

Thank you, I very much appreciate it!

Vim uses + and * for X11 selection (which I don't care about). Kakoune doesn't seem to use that. I'm unsure about Dance. If it's easy to make these an option, I think it'd be nice, but picking something between A-Z works too.

I think I've addressed all the above feedback including adding + and *, it should be pretty trivial to add new registers as long as they aren't already in use by Dance.

Sorry for the delay, this should be good to go now.
