Change default TS object bindings (helix-editor#3782)

* Change default TS object bindings

Changes 'match inside/around' bindings for:
- type definition from `c` to `t`
- comments from `o` to `c`
- tests from `t` to `T`

Also changes those for the `]` / `[` bindings.

* Update docs for changed keybinds
