appview/pulls: compress patch blobs using gzip
there is a very strange bug in the bluesky-pds implementation that
prevents blobs with the text `<svg` from being uploaded. it triggers a
500 because the underlying MIME type detection library assumes XML but
the provided MIME type does not match.
ref: https://github.com/bluesky-social/atproto/issues/3151
gzipping the content lets us upload this without any issues.
