config: Rename "Asynchronous Behavior" to "I/O"
"I/O" seems more descriptive than "Asynchronous Behavior", given that some ofthe GUCs in the section don't relate to anything asynchronous.Most other abbreviations in the config sections are un-abbreviated, but"Input/Output" seems less likely to be helpful than just IO or I/O.Reviewed-by: Tom Lane <tgl@sss.pgh.pa.us>Discussion:https://postgr.es/m/x3tlw2jk5gm3r3mv47hwrshffyw7halpczkfbk3peksxds7bvc@lguk43z3bsyq
