streams: Disable inline URL preview when rendering stream descriptions.

Browse Source 
We want to use the baseline features of bugdown, but not fancy things
like inline URL previews, since the whole structure of stream
descriptions is to have a single-line thing supporting some
formatting.

The migration part of this change fixes a bug encountered by some
organizations upgrading from older versions of Zulip.
