Description

test_api_version_compatibility fails on both master and v9.0-staging with:

IDL compatibility check failed with 2 errors:
Error in src/mongo/db/error\_labels.idl: ID0092: The parameter 'overloadRetryAfterMS' was present in the stable API but was removed.
Error in src/mongo/db/query/query\_optimization\_knobs.idl: ID0092: The parameter 'automaticCEPlanRankingStrategy' was present in the stable API but was removed.

Both parameters were renamed (not actually removed) by two unrelated, already-merged changes:
* SERVER-130142 renamed overloadRetryAfterMS to baseBackoffMS in error_labels.idl
* SERVER-127563 renamed automaticCEPlanRankingStrategy to internalQueryMixedPlanRankingStrategy in query_optimization_knobs.idl

Neither change added the corresponding exception to buildscripts/private/idl/compatibility_rules.yml's IGNORE_REMOVED_PARAMETERS_LIST, which is the standard mechanism for this (precedent: SERVER-123189, SERVER-128517).

This currently fails the required test_api_version_compatibility task on every patch against master and v9.0-staging.

Fix

Add both parameter names to IGNORE_REMOVED_PARAMETERS_LIST in buildscripts/private/idl/compatibility_rules.yml, each with a comment citing the rename ticket.
