Bump wicg-inert to 3.0.3 (#13878)

Not sure why dependabot hasn't made a PR for this yet, but there is a new
version of wicg-inert, which does not try to dynamically insert styles
anymore when those styles already exist. This will get rid of some of the
CSP violation warnings we get since getting rid of 'unsafe-inline'.
