https://www.mozilla.org/en-US/firefox/channel/desktop/#nightly doesn't show ARM64 builds

Description

Found by @lissyx. Follows #14414 up. nightly.mozilla.org doesn't show the ARM64 builds even when running on a Linux ARM64 machine. See screencast below:

We can't accurately detect ARM architecture via user agent strings on the web today, as many browsers now freeze this information. If you want the ARM Linux builds you can click the "All Languages and platforms" link shown in the screen grab.

An alternative is we could replace Linux download button with a drop down selector, similar to the ones seen for Firefox mobile here: https://www.mozilla.org/en-US/firefox/

This could then include 32/64/ARM64 options.

@JohanLorenzo I filed a wider issue to help address this, which could also hopefully improve the Linux download flow across the site. Let me know if you have any thoughts / opinions: #14613

@alexgibson, your proposal is great! Just for the record, Linux ARM64 doesn't ride the train, so it won't show up on beta and release soon. I'll keep you posted once we let it ride 🙂
