> This PR indends to add documentation for the ExecuteSteamCommand processor and improves the configuration experience by adding dependency between properties.
> I've noticed that the processor adds every Dynamic Property as environment variable even when it is a command argument. I didn't change this behavior because it might introduce a breaking change, but I'd change this behavior in a separate 2.0 only PR. Simply adding another regex check there would introduce the 4. regex check which is quite ugly so it would be a good opportunity for refactor. Another option would be to add validation for environment variables to ensure they don't contain {{{}.{}}}character, because most shells don't support it. But I'm not sure about that because there are commands that can utilize such env variables even though they are not common.
