Port yuzu-emu/yuzu#9058: "New transifex client needs migrating to" (#6389)

* Translations: new transifex client

Currently we're using the python client which uses an API that they
state will sunset Nov 30, 2022.

`tx push -s` actually appears to work properly, some of the other
commands require tweaking, like instead of suggesting `tx pull -a` in
dist/languages we need to suggest `tx pull -t -a`

* Set TX_TOKEN for transifex client

I did some tests on my own fork, and we're writing to ~/.transifexrc but
the client can't seem to read that file. maybe issue with $HOME or
something.

Workaround is to set TX_TOKEN environment variable and now the pesky
~/.transifexrc file is not needed.
