vim: Add neovim 0.11 default mappings (#28602)

Update the keymap to include:
https://neovim.io/doc/user/news-0.11.html#_defaults

This does conflict with `gr` replace with register though, is `gR` a
good alternative?

Release Notes:

- vim: Update the keymap to include: https://neovim.io/doc/user/news-0.11.html#_defaults
- vim: Replace with register has been remapped from `gr` to `gR`.
