tor-browser: update to 9.5.

This release includes important security updates to Firefox.

This new Tor Browser release is focused on helping users understand
onion services.

Tor's onion routing remains the best way to achieve end-to-end
anonymous communication on the Internet. With onion services (.onion
addresses), website administrators can provide their users with
anonymous connections that are metadata-free or that hide metadata
from any third party. Onion services are also one of the few
censorship circumvention technologies that allow users to route
around censorship while simultaneously protecting their privacy
and identity.

For the first time, Tor Browser users on desktop will be able to
opt-in for using onion sites automatically whenever the website
makes them available. For years, some websites have invisibly used
onion services with alternative services (alt-svc), and this
continues to be an excellent choice. Now, there is also an opt-in
mechanism available for websites that want their users to know
about their onion service that invites them to upgrade their
connection via the .onion address.
