Fix Run lens showing when lenses are disabled

I have disabled Rust Analyzer lenses in my VSCode settings, but noticed that the `Run` lens still showed. This surprised me, as the docs for `lens.run.enable` [state that it only applies when `lens.enable` is set](https://github.com/rust-lang/rust-analyzer/blob/25f59be62f6b915b44a4c2ec2defca56a5f766c1/crates/rust-analyzer/src/config.rs#L353-L355). I then found that where we set `LensConfig::run`, we don't check `lens_enable` like for the other settings. [We did this previously](https://github.com/rust-lang/rust-analyzer/blob/eab385e1f64f8e3b861effe91432785f8030191b/crates/rust-analyzer/src/config.rs#L1649), so this seems like a regression from refactoring. This PR tries to fix that.
