Simplify overrides to only pin browserslist

Drop the extra caniuse-lite/electron-to-chromium/baseline-browser-mapping/
node-releases/update-browserslist-db overrides added while working around
a registry-cache gap. The lockfile they produced is unchanged and already
verified via a real npm ci against the private registry, so removing them
from package.json's overrides list has no effect on the resolved tree.
