Add AppSync_BreakingChangeDetection hook to release pipeline

[ndejaco2]

Description of changes:

• This change adds AppSync_BreakingChangeDetection hook to the awscommunity registry pipeline.
• The cloudformation cli plugin for java and other languages now requires python >= 3.8. I went ahead and bumped this to unblock other resources in this pipeline.
• 1 known issue is that the resources written in go are unable to succeed due to the following error, which will be fixed later:
