fix: revert renaming of (management) console feature flag (#11706)

# Which Problems Are Solved

#11390 renamed "Console" to "Management Console". This included a rename
of the feature key to enable the management console to use the V2 API
for user creation. Due to the rename generated events would also be
changed, resp. existing events would be ignored, which leads to
inconsistency in the data model.

# How the Problems Are Solved

Renamed the key back to `KeyConsoleUseV2UserApi`.
And added a comment to prevent future issues.

# Additional Changes

None

# Additional Context

- relates to #11390 
- backport to v4
