Code review comment for ~sergiodj/ubuntu-docker-images/+git/telegraf:1.19-21.10

Athos would probably be better to review than me, but I know he's off until next week.
I wanted to at least test your image builds, but unfortunately my local system's docker doesn't work, so will instead trust CI to build/test.

Verified the new version is 1.19.2 in impish, and things seem to be substituted correctly.

LGTM, +1
