refactor(nvim): Keymap updates for git, symbol search & save/quit

- Treesitter: `]a` -> next arg, `[a` -> previous arg, `]T` -> next test
- git: Revert Previous & next hunks to `]g` & `[g`
- git: Remove `<space>gK` for hover blame-line: use `<space>gL` instead
- save: Save all files with `<C-s>`,
- exit: Quit without saving with `<C-q>`: won't exit with unsaved files:
  sometime you don't want to save files
- Search symbols with `<space>s` & `<space>S` instead of `<space>cs` &
  `<space>cS`
