Update the text on MaveMD and About pages to show the current number of variants and scoresets #593
Description
There is hardcoded text on the MaveDB and About pages with counts that don't match the data included in MaveDB:
"MaveMD currently contains 438,318 variant effect measurements mapped to the human genome from 74 MAVE datasets spanning 32 disease-associated genes."
Based on the values in MAVE_MD_SCORE_SETS list, the 32 genes is correct, but the number of score sets should be 67. The number of variants is more involved to calculate, but @bencap previously wrote a script for this that would count only those within ACMG-classified ranges.
These counts should be updated to reflect the current data, and possibly be stored or calculated dynamically to keep them up to date going forward.
