chore(nvim): Neovim config cleanups

- Use newer installation for Lazy.nvim
- Treesitter: ensure_install sql, bash, jsonc, python, dockerfile
  plugins
- Completion: Use <ctrl+y> to accept. <enter> to accept was interfering
  with completions that were suggested at end of the line and you don't
  want to accept but just want to go to the next line
- Snacks: disble the abhorrent *smooth* scrolling
- Whichkey: More time before pop-up shows (450ms)
