Fix patch for #23247: Communicating security expectations for .onion

While working on #33533 (moved) I realized that in the switch to ESR68 (#30429 (moved)) the patch for #23247 (moved) was ported incorrectly. The original patch for ESR60 was 651e4ef7de3e and the mistake was introduced in revision https://github.com/acatarineu/tor-browser/commits/30429+6 (see comment in https://trac.torproject.org/projects/tor/ticket/30429#comment:26).

My understanding is that in the original patch, the block of if (isHttpScheme && IsPotentiallyTrustworthyOnion(innerContentLocation)) { was moved from https://github.com/acatarineu/tor-browser/commit/651e4ef7de3e#diff-b6c711bd6646bb39271394da3fc55d0cL754 to https://github.com/acatarineu/tor-browser/commit/651e4ef7de3e#diff-b6c711bd6646bb39271394da3fc55d0cR737 in order to allow mixed contents in workers for the .onion case (which would get disallowed otherwise).

However, in ESR68 there's IsPotentiallyTrustworthyOrigin with includes IsPotentiallyTrustworthyOnion. So, I think this block: https://github.com/acatarineu/tor-browser/commit/6301359f2742d070b1b4149d13c388e96b1b8080#diff-b6c711bd6646bb39271394da3fc55d0cL778 should not be removed, since it's not the same as the one that is added in https://github.com/acatarineu/tor-browser/commit/6301359f2742d070b1b4149d13c388e96b1b8080#diff-b6c711bd6646bb39271394da3fc55d0cR771.

I think this is not a security issue, the result of this bug is that we are not allowing cases that we should (all cases of IsPotentiallyTrustworthyOrigin that are not .onion).
