rust-analyzer.cargo.extraEnv is not applied when running tests

[connor4312]

rust-analyzer version: 0.4.1250-standalone (97b357e 2022-10-18)

rustc version: rustc 1.63.0 (4b91a6ea7 2022-08-08)

relevant settings: N/A

1. Set rust-analyzer.cargo.extraEnv with some object
2. Consume the environment variable you set with an option_env!() or similar during compilation
3. Click on a "run tests" code lens
4. Notice the environment variable was not applied 🐛

Hi - I've just started learning the code base and decided to triage this bug as an exercise:

• That config rust-analyzer.cargo.extraEnv only affects cases where rust-analyzer launches cargo directly.
• The "Run Tests" clickable annotation is executed by the VS Code extension via vscode.tasks.executeTask and not rust-analyzer.
• I think this config rust-analyzer.runnableEnv should work see: https://rust-analyzer.github.io/manual.html#setting-runnable-environment-variables.

This is now named rust-analyzer.runnables.extraEnv.
