Mark addGrantedAuthorityCollection Value Parameter Nullable

Browse Source 
The io.spring.nullability plugin 0.0.16 upgrade tightens NullAway
analysis and flags the raw Collection<?> element passed into
addGrantedAuthorityCollection(Collection, Object) as possibly null,
even though the method already null-checks it internally.

See gh-19670
