api: fix galaxy_feature_flags configuration

By overriding the galaxy_feature_flags configuration for enabling the EE
then we loose all other default values from galaxy_feature_flags.
Prior pulpcore 3.23 this wasn't a problem but starting 3.23, if the
galaxy_feature_flags dict doesn't have some required key then dynaconf
will fail (like during the database migration).

The `execution_environments` configuration within GALAXY_FEATURE_FLAGS has
always been set to True by default so there's no need to define it explicitly.
