Multiline config fields for Workflows submit when enter is pressed

[Aevyz]

Steps for Recreation:

1. Deploy LLM openrelik module
2. Add LLM to a workflow
3. Press the config button
4. Attempt to enter a prompt that requires two lines
5. When pressing enter, the field will save instead of letting you type in a new line

Expected Behavior: Pressing enter lets you type on a new line
Actual Behavior: Pressing enter saves the config

Using Firefox if relevant

I don't think this is an issue specific to this particular worker. UI logic is defined in openrelik/openrelik-ui.
