refactor(neovim): Git operation enhacements

- Use gitsigns to do file diff against index
- gitsigns: Use `[h` `]h` to traverse hunks instead of `[g` `]g`
- gitsigns: `<leader>gQ`: Project hunks to quickfix list
- gitsigns: `<leader>gs` acts as toggle to stage & unstage
- diffview: `<leader>gD` Diff all files against index
- Lazygit: Consistent keymap descriptions
