build(docs-infra): update main bundle size (#31839)

PR #31839 contains perf and code cleanup changes that add 48 bytes to the
main bundle size. Perf gains and code clarity justify this increase.

Unfortunately the size verification job is rejecting this PR as it reports
size gains from a fixed size and not relative increase of size from a particular PR.

It was decided during the internal team discussion to bump up size limits to
correctly reflect current state of the master and increase from this PR.
