Build for Linux ARM64 in CI

[kevaundray]

Problem

We currently have behaviour that only gets triggered on linux arm64 machines. See #3531.

This is currently not tested in the CI.

Happy Case

We build for linux arm64 in CI to ensure that that logic gets tested. In particular, we want to test for:

• We can build nargo on that arch
• We can compile on that arch
• We will not be able to prove/verify because as of writing this, the b binary does not produce linux arm64 builds.
