Makefile For All Hooks #478

As developer/maintainer of the secureCodeBox
I want to reduce the complexity of installing unreleased hooks
so that testing locally and in the CI becomes more easy

To tackle this issue, we want to introduce Makefiles for each hook.

• declarative-subsequent-scans
• finding-post-processing
• generic-webhook
• notification-hook
• persistence-defectdojo
• persistence-elastic
• teams-webhook
• update-field

See #476
