Updates the Asana documentation, which was a detailed version
of the Zapier documentation with screenshots specifically for
Asana, to instead start with the basic incoming webhook steps
and then point to the general Zapier documentation to complete
the integration.
This will be easier to maintain moving forward in the short
term as ideally we'll migrate to a system that documents all
of the integrations with Zulip that are available via Zapier.
Also, updates the current Zapier documentation to mention
Asana as one of the apps that can be integrated with Zulip.
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.
The "subdomain" label is redundant, to the extent it's even
accurate -- this is really just the URL we want to display,
which may or may not involve a subdomain. Similarly "external".
The former `external_api_path_subdomain` was never a path -- it's a
host, followed by a path, which together form a scheme-relative URL.
I'm not quite convinced that value is actually the right thing in
2 of the 3 places we use it, but fixing that can start by giving an
accurate name to the thing we have.
