refactor!(vertico): fix embark-collect and rebind to C-c C-l

BREAKING CHANGE: `embark-collect-snapshot` has been renamed upstream to
`embark-collect`. Since the `C-s` mnemonic doesn't really make sense
anymore, I've moved the binding to `C-c C-l`, which has the nice bonus
of being next to the similar `C-c C-;`, and being nicer.
