build(notifier): Make the Jakarta REST API dependency a constraint

Prevent consumers of the notifier to upgrade the Jakarta REST API
because the Jira library requires version 2.1.x which still has the
"javax" instead of the "jakarta" package namespace.

Note that because constraints do not actually introduce a dependency [1],
the constraint needs to be declared additionally.
