bump: :completion corfu + evil-collection

The `evil-collection` upgrade is needed due to a recent breaking change
in Corfu's setup and teardown functions. `evil-collection`
`:after`-advised these with `#'evil-normalize-keymaps`, which accepts
only 1 optional argument. This was fine because the functions took no
arguments, but some have been introduced recently. Trying to initiate
completion would now throw a "too many arguments" error, and due to the
partial operation on the keymaps, make Emacs mostly unusable.
