Add multi-line text area input to actions and module configuration

[cyberblaststudios]

Is this a feature relevant to companion itself, and not a module?

• [X] I believe this to be a feature for companion, not a module

Is there an existing issue for this?

Describe the feature

It would be nice to have a text area (multi-line) input for action inputs and module instance configuration options.

Usecases

• Pasting in an SSH key as an authentication option (sometimes they require multi-line)
• For the generic-ssh module, for example, it would be nice to paste in a line-break delimited list of commands in the action inputs.

All text inputs would benefit now that there is more widespread availability to use dynamic variables and expressions.
