doc: Correct the description about the length of pg_stat_activity.query. 

pg_stat_activity.query text is truncated at 1024 bytes. But previously
the document described that it's truncated at 1024 characters.
This was not accurate when considering multibyte characters.

Back-patch to v10 where this inaccurate description was added.
