Remove all but the initial go-cve-dictionary related alembic migrations

[evonide]

The go-cve-dictionary third-party dependency maintains its own tables. If there is an update it will automatically migrate/update the table structure.

Currently, Vulncode-DB explicitly ensures over alembic migrations that the data models are in sync. However, this breaks if go-cve-dictionary is run before Vulncode-DB was upgraded to the newest version as some columns or database modifications might have already happened through go-cve-dictionary.

1. Change all initial alembic migrations in migrations/versions/82f8f48c6ee6_initial_layout.py to be create if not exist.
2. Remove all alembic upgrade instructions related to go-cve-dictionary from all migrations after that.

This way it is expected that go-cve-dictionary will be run at least once if there have been any updates.

• How can automatically detect and enforce this to avoid unexpected breakages?
