Benchmarks don't have a "▶Run" button

editor or extension: vs code

relevant settings: none

code snippet to reproduce:

// benches/bench.rs
fn main() {
    println!("bench");
}

This does not display a "Run" lens, even when the benchmark is configured with harness = false in Cargo.toml (which isn't necessary for integration tests, they always show a "Run" lens).

@A4-Tacks can we treat crate-root fn main as runnable regardless of cfg(test), and add a regression test fixture for a cfg:test crate with fn main() to ensure the runnable is still produced. This should make benches behave like integration tests in terms of showing a Run lens.

IDK, I don't use this feature
