--with-tor-browser-version appears to be unsupported but is still in tor-browser-android mozconfig

browser/config/mozconfigs/tor-browser-android adds a def for --with-tor-browser-version on local builds, but not tbb ones, and browser/config/mozconfigs/tor-browser has no reference to the same variable. local dev builds of tor-browser for android saying "mozbuild.configure.options.InvalidOptionError: Unknown option: --with-tor-browser-version"

in 74fcc2ed it appears to have mostly been removed, except the localbuild option for android, so I suspect an oversight
