Vaclav Mlejnsky d5f7360491 Add missing in(), out() & command() method definitions for gm package (#29475) ...

Definitions for [gm](https://github.com/aheckmann/gm) package are missing 3 methods - `command()`, `in()` and `out()`.
Usage of these methods is described [here](https://github.com/aheckmann/gm#custom-arguments).

Also, this should resolve #24795
