Donating action-rust-aws-lambda

[miere]

Hi,

As one of my projects was finally migrated to Github Action, I needed a way to release AWS Lambda compatible binaries. Thus I decided to put some lines of code together and create a custom action the generates this build for me. It is a port of the steps described by the official AWS Lambda Runtime for Rust.

Just as the toolchain action is useful for me, I believe my ad-hoc action might be useful for other people too. Therefore I decided to donate it to the actions-rs, of course, if you think it makes sense.

Here is the original source code. Please let me know your thoughts and how can I help in the process.
