Add ARM-binaries downloads to the Linux Download Page

Issue description:
On the Linux Download page (godotengine.org/download/linux/), there are currently only links for the x86 (and x86_64) versions, for the ARM-binaries users (currently) have to look in the archive. In my opinion, it is very unintuitive, because the archive contains previous releases (as website says).
A possible solution would be to add download links for the ARM-binaries or add a link to the archive stating the ARM-binaries can be found there.

4.2 ARM binaries didn't work correctly (unlike 4.2.1 and later), so I'd consider unlisting them at the same time.

ARM is now listed on the Linux download page for 4.3 (in the All downloads section), but not for 3.6.

Ideally, we should automatically replace the main download link based on the user's architecture, but I'm not sure if it can be detected from JavaScript.
