Bug 1707635 - update documentation how to ingest specific queues with new names (#7118)

Bug 1679162 had split the parsing of logs for failed tasks into multiple dimensions:
- monitored by code sheriffs or not
- raw or JSON data

This added 4 new queues:
- log_parser_fail_raw_sheriffed
- log_parser_fail_json_sheriffed
- log_parser_fail_raw_unsheriffed
- log_parser_fail_json_unsheriffed

The sheriffed ones handle the autoland and mozilla-* trees watched by code
sheriffs, the unsheriffed ones all other trees (e.g. 'try').

 You will see a list of activated queues.  If you wanted to narrow that down, then note
 which queues you'd like to run and add them to a comma-separated list.  For instance, to
