Refactor Mako actions, fix setup-git command & add exec-ryujinx-tasks command (#3)

* Create multiple actions to make Mako easier to use

* Add smoke tests for the new actions

* Check if the required env vars aren't empty

* Fix working directory for execute-command

* Fix action_path references

* Fix broken setup_git command

* Add exec-ryujinx-tasks subcommand

* Ensure python and pipx are installed

* Improve help output

* Add required environment variables to README.md

* Add small script to generate subcommand sections automatically

* Adjust help messages for ryujinx tasks as well

* Remove required argument for positionals

* Add exec-ryujinx-tasks to subcommands list

* Apply black formatting

* Fix event name for update-reviewers
