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.
We create "event-filter-instruction.md" and add it to
"create-bot-construct-url.md". This allows the user to keep track of the
supported event types for most of the integrations that implement this
feature. Note that not all integrations use "create-bot-construct-url.md".
We also need to rename "function" to "view_function" to make this change
type-check.
This is relevant to #18392.

Updated create-bot-construct-url-indented.md file with
guidelines on how to URL-encode stream name and topic
name. The hyperlink added will solve the issue for those
who use emoji in stream name or topic name.
Tweaked by tabbott to edit the copy and update the non-indented
version as well.
Fixes#16430.
