Signal: Remove GIPHY support due to Facebook involvement [GitHub Issue]

Looks like it was shut down pretty quickly. As the responder notes:

"We have always used a proxy for our requests to GIPHY, and will continue to do so. There should be no harm in continuing to use it."

Slightly misleading title as one would assume this is an announcement of removing support for GIPHY, not a closed pseudo-bug report.

Moxie also said they're going to keep it. https://twitter.com/moxie/status/1261342005658935297?s=20
