The conversion script for help-beta assumes that all items in a numbered
list start with 1. which was a wrong assumption. This commit attempts to
fix that. We are not introducing any lint step to tackle this since it
will be easy to just check for this again before the cutover happens.
We do not change this for `numbered-list-examples.md` since that example
shows how the current numbered lists work and we might still want to
show that. We can decide what to do with that file once the time of
cutover arrives.
This commit updates the pencil icon in help/edit-a-message and
help/delete-a-message to reflect the changes in commit 735a42d, which
updated the pencil icon of the message on-hover options.
