Remove Pipeline Activity Limit - Follow-up (Database)
Background
Backend code Pipeline Activity Limit was removed as of: #368195 (closed)
But there is still the column in the database that records this limit that should also be removed.
Proposal
Due to the safety reason and documentation, this database removal will need to be done across multiple minor versions per https://docs.gitlab.com/ee/development/database/avoiding_downtime_in_migrations.html#ignoring-the-column-release-m
Column ci_active_pipelines
from table plan_limits
should be removed
