Third Party Lookups: the returned protocol instance icons are not Matrix Content URIs

[giomfo]

Contrary to the documentation (https://matrix.org/docs/spec/client_server/r0.4.0.html#get-matrix-client-r0-thirdparty-protocols), the returned protocol icons are not mxc:// URIs.
The client gets https URLs (like "https://matrix.org/_matrix/media/v1/download/matrix.org/DHLHpDDgWNNejFmrewvwEAHX").

Note: The documentation is correct here, the server should not return non-mxc content URLs

Contrary to the documentation (https://matrix.org/docs/spec/client_server/r0.4.0.html#get-matrix-client-r0-thirdparty-protocols), the returned protocol icons are not mxc:// URIs.

@giomfo I cannot see where the docs specify the URI protocol of a returned icon link. The only information that I was able to find there about the icon parameter is the following:

Parameter	Type	Description
...	...	...
icon	string	Required. A content URI representing an icon for the third party protocol.

Also, I could not find anything in the current docs. The text passage closest to it is this one.

Can you specify, where the docs say that icon URIs should only be of protocol mxc?
