"the Tor Browser" -> "Tor Browser"

There are still some cases where we say "the Tor Browser" on the support portal.

I checked with Richard and they are fine with unifying our language into calling it Tor Browser.

I think I am just unifying everything to how people talk this year, that is, I am hoping this change surprises nobody.

Example fix, on mullvad-browser/does-this-mean-tor-browser-will-get-less-attention:

-We are also working hard on bringing the Tor Browser for Android up to par
+We are also working hard on bringing Tor Browser for Android up to par

This naming convention topic is also a candidate for a new section in the https://gitlab.torproject.org/tpo/team/-/wikis/Tor-User-Documentation-Style-Guide. (Is there already a naming style guide? I searched around on google for a while and only found https://styleguide.torproject.org/ so either no there isn't one or yes there is but it is well hidden which is not good news for a style guide. :)
