doc: Remove link to JSON support in the SQL specification

michaelpq · michaelpq · commit ee5822361dab · 2022-01-06T11:41:09.000+09:00
The link used in the documentation is dead, and the only options to have an access to this part of the SQL specification are not free. Like any other books referred, just remove the link to keep some neutrality but keep its reference.
