NullAway 0.13.6

(NOTE: originally these notes appeared with the 0.13.5 release, but that release was pushed
incorrectly due to an error in our release process.)

Includes various bug fixes, particularly in JSpecify mode. Also, the nullaway-annotations
artifact now includes a @Contract annotation. NullAway also now has a built-in handler
to reason about field initialization in classes managed by Jakarta Persistence.

Work has begun on support for wildcards in JSpecify mode. Currently, this support is off
by default, guarded by the configuration flag HandleWildcardGenerics. The support still
has multiple known bugs, and we do not yet recommend enabling it.
