new c822ac8f04c docs: fix off-by-one line anchor in docker tutorial
DRUID_LOG4J link (#19487)

docs: fix off-by-one line anchor in docker tutorial DRUID_LOG4J link
(#19487)
The `DRUID_LOG4J` bullet in the Docker tutorial points at line 52 of the
example `distribution/docker/environment` file, but that line is empty.
The actual `DRUID_LOG4J=` entry is on line 51, so the anchor lands one
line below the target. Off by one.
Update the anchor from `#L52` to `#L51` so the link lands on the
`DRUID_LOG4J=` row in the current file layout.
