Some variant tags refer to CMG

[mathob]

Describe the bug
The data sharing variant tags seem to presume that all users are CMG (is that Centers for Mendelian Genomics?) participants which I don't think is true for this seqr instance. So I suggest removing things like "..you are notifying CMG staff.." and reviewing what data sharing tags are appropriate to maintain. Also the Discovery tags seem really useful but it wouldn't hurt to have a reference to a webpage describing them a bit more (what is Tier 1 vs tier 2?). I was unable to find any such page online.
