Remove read-only server settings lc_collate and lc_ctype
The GUC settings lc_collate and lc_ctype are from a time when those locale settings were cluster-global. When those locale settings were made per-database (PG 8.4), the settings were kept as read-only. As of PG 15, you can use ICU as the per-database locale provider, so examining these settings is already less meaningful and possibly confusing, since you need to look into pg_database to find out what is really happening, and they would likely become fully obsolete in the future anyway.
