update: add find --clear option

[leyiang]

Add new flag for find command. run find --clear will clear the previous search input.
I usually use find command to search folder and enter, with find --clear I can have this:

[[manager.prepend_keymap]]
on   = "l"
run  = ["plugin smart-enter", "find --clear"]

open folder and also clear search, then don't need to manually type "/" + "Enter" to clear search.

escape --find is exactly what you're looking for, https://yazi-rs.github.io/docs/configuration/keymap#manager.escape
