Fix audio tooltip logic

[AaronFeickert]

Earlier work by @osiewicz in #21931 aims to fix audio control tooltips in the title bar to close #21929. However, its logic is not quite correct, and does not match the toggle behavior for the controls.

This PR corrects the logic to match the toggle behavior for the controls. It also updates capitalization and wording for consistency.

Release Notes:

• N/A

It's not clear why Linux and Windows are failing the linter. There's no failure on macOS, nor locally (which happens to be macOS as well). Insights on this would be appreciated.

There are two implementations of the call crate, depending on which platform you're using. You'll need to re-implement the function you added in the cross-platform implementation as well :)

Ah, got it! I'm new to the codebase and certainly appreciate the information. I just started using Zed and am excited to contribute back to it.

No worries! It's a big codebase and things are always changing :D

Glad you're excited, we're happy to have you :D
