[feat] Filter in command list

[jonasrafa]

Describe the problem

I don't think this would be a priority at the moment, but since I couldn't find any issues about it, I decided to create one.

Currently, there is no way to filter lists within extensions with the template ui

Describe the solution you'd like

Add a filter system, an example of which is on Raycast

Yes I do have plan for this dropdown menu, didn't have time to implement it yet.
I can try to prioritize this.
