Renaming for new subscripting mechanism

Browse Source 
Over at patch https://commitfest.postgresql.org/21/1062/ Dmitry wants to
introduce a more generic subscription mechanism, which allows
subscripting not only arrays but also other object types such as JSONB.
That functionality is introduced in a largish invasive patch, out of
which this internal renaming patch was extracted.
