feat: update translate task form layout

[edward-ly]

Resolves#216. Parts of the new custom translate form component are adapted from the translate modal in the Text app.

I'm wondering if we want the user to select the model. Didn't we say in the past we let model selection be done by the admin? @julien-nc

This is hidden under "show advanced options" right now as we have it in every other task type

You seem to not use the input shape defaults right now I think, it would be good to have them used as pre-set languages @edward-ly
They should be available as translateTaskType.inputShapeDefaults

Thanks for the catch! That should be fixed now.

Nice! I hope you don't mind: I added a fix to make the output text field show and hide the "copy" button when the value changes. I realized it was broken in the generic form as well because the wrong event was emitted in AssistantFormOutputs so i fixed this one too.

2 potential small changes.
Otherwise, good to go 👍
