Add ability to keybind search filter (#30327)

Useful for large monorepos with many subdirectories, users can keybind a
filter to their commonly used directories.

Release Notes:

- Added a new `included_files` field to the `DeploySearch` action to
automatically pre-fill which files to include in the search. This lets
you use a keybinding to search in a particular folder or for a certain
set of files.
