Upgrade Hugo to 0.111.1 and fix doc issues

[chalin]

• Closes Bump hugo-extended from 0.110.0 to 0.111.1 #2452
• Upgrades to Hugo 0.111.1
• Fixes a bug in a page that was missing an end-tag marker for a shortcode
• Fixes YAML sample in 2022 blog since some of the content is meant to be in comments (and otherwise results in pretty-printed YAML).
• Drops unnecessary quotes around shortcode arguments

The only changes to the generated site files, other than the updated Hugo version, are due to pretty-printer changes and the YAML fragment update:

$ (cd public && git diff -bw --ignore-blank-lines -I "Hugo 0\.") | grep ^diff | grep -v \.xml
diff --git a/blog/2022/k8s-otel-expose/index.html b/blog/2022/k8s-otel-expose/index.html
diff --git a/docs/demo/services/shipping/index.html b/docs/demo/services/shipping/index.html

Note the missing "/" at the end here.

The <REPLACE: your ...> (used here and two places below), confused even Prettier. This way of illustrating an entry that has parts to be replaced seems better / less confusing for the pretty-printers.
