Permit other CPU architectures in the Arch Linux PKGBUILD

[pvshvp-oss]

Rate-Mirrors appears to run fine on aarch64 and will likely run fine on other CPU architectures too. Perhaps we should change the architecture from x86_64 to any in the PKGBUILD file.

Suggested edit:

arch=('x86_64')

to

arch=('any')

Here is a screenshot of rate-mirrors running on a phone:

Hello!
I've updated the github action so it builds aarch64 version and makes it available in Github releases, e.g. v0.9.1.
I also updated both AUR packages:

• rate-mirrors - arch=('any')
• rate-mirrors-bin - arch=('x86_64' 'aarch64')
