Change the credential provider row active indicator to a CheckButton

Because I noticed that Adw has a style that is for this sort of thing.
Opened Credential prefs, and changed selected provider. Also checked that clicking the check button didn't accidentally change its state without changing the row, and that it could not be selected by keyboard separately from the row.
