chore: update browserlist and babel targets to chrome/firefox 89 (MetaMask#22521)

## **Description**

IIRC, we've documented extension browser support for versions 2 years
old and newer (I can't find this documentation now though). Chrome and
Firefox 89 were released in 2021, so the version in this PR should be
good to go.

We could go with even newer browser versions, but it was a struggle
getting it to work for v89, so I didn't try to take the versions any
further.

This PR also reduces the chance of seeing a lavamoat caused
`RegExpCompiler Allocation failed - process out of memory` error
(MetaMask#21006).
