The [[https://gitlab.wikimedia.org/repos/ci-tools/browserslist-config-wikimedia/-/blob/330a4f8d788753191dbe9df5bb1411596900d5b3/basic.json|basic list]] in browserslist-config-wikimedia should match Grade C in the [[https://www.mediawiki.org/wiki/Compatibility#Browser_support_matrix|browser support matrix]]. As part of T288287, we want to drop IE11 from Grade C, so IE11 should also be removed from the basic list.
Additionally, the browser support matrix specifies that Grade C includes Edge 79+, but basic.json lists 12+; this should be updated to 79+.
[ ] Remove IE11 from basic.json
[ ] Increase minimum Edge version from 12 to 79 in basic.json
[ ] Check that `Android` is correct or if it needs to be `ChromeAndroid`
[ ] Link basic.json (and modern.json) on https://www.mediawiki.org/wiki/Compatibility
