Drop Feature Flags Version Column
What does this MR do?
As version 1 (legacy) feature flags have been completely removed and phased out, we can now safely remove the version column, as well as the ActiveRecord association between feature flags and legacy scopes.
The legacy scopes will be cleaned up in a later MR to reduce MR size.
Changelog: removed
How to setup and validate locally (strongly suggested)
Go to a project, go to Deployments > Feature Flags and make and edit some feature flags.
