Upgraded Rustler dependencies to 0.30, to work with OTP 26

What?

Upgraded Rustler Elixir and Rust dependencies to 0.30

Why?

The current blake3 elixir library was not compiling with OTP 26 and was giving error.

Compiling crate blake3 in release mode (native/blake3)
   Compiling rustler v0.22.2
error: failed to run custom build command for `rustler v0.22.2`

Testing

• Unit tests are working fine.
• Have added new Elixir and Erlang versions to the ci.yml

@madclaws Thank you for the fix! I dropped 1.12 from the test matrix due to an issue with Application.compile_env/3 your changes should be available in 1.0.2
