Several integration docs instruct the user to create a bot, but don't
specify that the type of bot should be "Incoming webhook".
Renames create-a-bot.md -> create-an-incoming-webhook.md for clarity,
and replaces all incomplete instructions with this macro.
Renames bot_types.png -> bot_types_incoming_webhook.png and updates
the image with a screenshot of the latest UI.

Also, rewrite it as a block processor, so that it works correctly
inside indented blocks.

I have updated the docs for the Jenkins integration to include number
for ease of read as well as switching over to the new
{create-a-bot-indenmted.md} template to allow the continuation of
numbers.
Fixes part of #17633.
