[none-ls] Deprecating builtins with unmaintained upstream or native LSP replacement

[charliie-dev]

nvimtools/none-ls.nvim#81
nvimtools/none-ls.nvim#77

That PR will lead to some changes to our format/linting mechanism, since we explicitly disable formatting ability form LSs.

I suggest doing the following:

1. Pin none-ls' commit 'til further decision is made.
2. Decide to use other format/ linting management plugin or change our lua/modules/configs/completion/formatting.lua to comply w/ none-ls.

Should we pin the previous commit of this commit? the warning message is just annoying

I choose this commit b/c i think we need to let users know that they might need to update their user config.
yeah, i know it's a bit annoying, but it still serve as a reminder tho.

The latest commit nvimtools/none-ls.nvim@793c607 add a way to supress the deprecation warning, I think it's better for use.

I tend to just remove rustfmt for us and keep using none-ls. Users should do their own changes for upstream changes.
