RustTest doesn't recognize tokio::test

Start by locating the :RustTest implementation and its test coverage for recognizing Rust test functions. Compare the supported #[test] form with the reported #[tokio::test] form. Done means placing the cursor on an async Tokio test function and running :RustTest finds and runs that test.

• rust.vim version: Using latest via vim-plug

Steps to reproduce:

• Put cursor on test function name
• :RustTest

Expected vs. actual behavior:

• Expected: runs the test
• Actual: finds no test under cursor

Works:

#[test]
fn test() {}

Does not work:

#[tokio::test]
async fn a_test() {}

Paste debugging info from the Rust Vim plugin via one of the following
commands: :RustInfo, :RustInfoToClipboard, or :RustInfoToFile <filename>.
