feature: Update LSP keymaps after vim 0.11

[dgmora]

Did you check the docs?

• [x] I have read all the LazyVim docs
• [x] This is not a request for a new or existing extra (see above)

Is your feature request related to a problem? Please describe.

Vim 0.11 adds some default keymaps which are similar to some defined by LazyVim https://neovim.io/doc/user/news-0.11.html

Lazyvim gr keymap will trigger before those set by neovim, plus some other are redundant.

Describe the solution you'd like

Remove the keymaps that are already defined by neovim

Regarding C-s (signature), it is is a very common keymap for tmux and for me it clashes (same with C-k from lazyvim, I also use it for tmux). But I guess that's the default now.

Describe alternatives you've considered

Change it in my config
