Release prep for 11.5a13

Also includes removal of HTTPS-Everywhere extension from Desktop. So far I've successfully built linux x86_64 with this branch and can confirm we can still connect to https://washingtonpost.securedrop.tor.onion despite the extension removal 😄

Android failed on the first attempt due to needing to update the android-components tag to build3 (which @pierov signed).

Building currently on tb-build-05, will let you all know if it succeeds.
