integrations: Add incoming webhook macro to relevant docs.

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.
