Edit: For PLG, show the used model in the codelens, allow quickly repeating an edit with a different model

[umpox]

What:

• We support changing models for Edits
• It would be nice if users had a way to quickly retry an edit using a different model.

How:

• Show the model name at the end of the lens
• We can also include the model icon, as this is supported in codelenses
