Update browserslist

Summary

Updates the browserslist and caniuse-lite npm packages

Reviewing notes:

There should only be changes to the yarn.lock file in
this PR. Check that there is only 1 caniuse-lite package
reference in the yarn.lock file (the intent of this
update is to ensure that caniuse-lite is on the latest
version and that there aren't multiple, conflicting
versions that different tools might see).

If everything looks fine, please approve this PR and then
land it (either with the Big Green Merge Button ™️ or by
using git land <this pr #> in a terminal).
