Update gnomAD Variant Co-Occurrence link in seqr

[lynnpais]

Is your feature request related to a problem? Please describe. The gnomAD co-occurrence link is showing in seqr if the variants are present in v4 but Variant Co-Occurrence data is only calculated for variants in v2.

Describe the solution you'd like Would it be possible to show the Variant Co-Occurrence link if the variants are also present in gnomAD v2?

Additional context Example: https://seqr.broadinstitute.org/project/R0594_rare_genomes_project_gen/saved_variants/variant/SV0158592_1912676016_f040474_r,SV0158593_1912681648_f040474_r - gnomAD Variant Co-Occurrence link shown but these variants are not in gnomADv2
