TFS-25574:  The text for uploading a group avatar specified specific
pixel dimensions of 990px/100px.  Users were complaining about cropping
issues.  After talking with Nancy I think we should just remove this
text to match the personal stream avatar upload page which does not
include the text regarding pixel dimensions.
