CloudCannon's edit split the 1-5 numbered "Build the automation" list
into two lists that restarted numbering at "Set up the trigger," and
reindented the bullets inside both annotate blocks to 10 spaces, which
python-markdown rendered as a joined paragraph with literal dashes.

Restore the continuous 1-5 list, move the add-automation gif inside
step 2 with 4-space continuation indent, and fix the annotate block
indentation back to 4 spaces so the choices render as proper bullets
and the annotation tooltips work. Preserves the Next Steps / Light
Effects button added in #866.

Supersedes #865, which had the same fix but conflicted after later
edits to the file.
