can't use cargo in this action

[try-agaaain]

I want to use this action to build a rust application on aarch64, but when I run cargo, this action will suddenly stop and exit. Frustratingly, no helpful prompts are given after exiting. Failed action

By the way, I can build normally on my local aarch64 machine.

The problem is that cargo tries to fetch the crates.io index and fails with OOM. It is a known issue!

See rust-lang/cargo#10781 (comment)
Another solution is to use the new SPARSE protocol - https://blog.rust-lang.org/2023/03/09/Rust-1.68.0.html#cargos-sparse-protocol.

Thanks @martin-g! Since with this we already have 2 issues related to Rust, it's probably time I'll start adding a specific section to the readme about solutions to common problems.

@try-agaaain can you confirm if this fixes the issue?

Yes, it works fine now, thanks a lot.
