Add REJECT action to Network Firewall rule group stateful rule actions

[ddericco]

Description

Adds formal support for the REJECT stateful rule action in the aws_networkfirewall_rule_group resource by adding acceptance tests and updating the documentation. Note that setting the REJECT action was possible previously due to the validation in networkfirewall.StatefulAction_Values(), but was not documented nor checked as part of the acceptance tests.
