Remove unnecessary @ts-ignores
Use @ts-expect-error instead of @ts-ignore for external dependencies

In certain scenarios(when the iframe's domain is the same as the parent page)
 the jitsiLocalStorage key from local storage is
included in the serialized local storage and then
propagaded to the parent page. This way we end up with recursion which
grows the localStorage infinitely.

Due to local storage limitations we might end up making the URL huge
when we save the state there. Avoid the issue at the root by never
storing URLs in that case.

Closes: https://github.com/jitsi/jitsi-meet/issues/11567

There should be no need to use the workaround when visiting the site normally.
