feat: add subcommands to :GhActions

This introduces the following commands:

- `:GhActions` or `:GhActions toggle` toggles the `gh-actions` split
- `:GhActions open` opens the `gh-actions` split
- `:GhActions close` closes the `gh-actions` split

BREAKING CHANGE: `:GhActions` now toggles the split instead of only opening it.

Fixes #12
