Update comments about index parallel builds
Commit b43757171470 allowed parallel builds for BRIN, but left behind
two comments claiming only btree indexes support parallel builds.
Reported by Egor Rogov, along with similar issues in SGML docs.
Backpatch to 17, where parallel builds for BRIN were introduced.
Reported-by: Egor Rogov
Backpatch-through: 17
