Add Mac OS tracy info to profiling docs (#13826)

## Explanation

I got kind of lost on this earlier (the Tracy docs are not very helpful)
and required some assistance, so I thought it might be helpful to add
this somewhere in the profiling docs. The way it's presently inserted is
kind of awkward, but I don't know enough about the other operating
systems to make similar sections for them, which I think would be
helpful, since it's going to be different on each one.

 It has a command line capture tool that can record the execution of graphical applications, saving it as a profile file. Tracy has a GUI to inspect these profile files. The GUI app also supports live capture, showing you in real time the trace of your app. The version of tracy must be matched to the version of tracing-tracy used in bevy. A compatibility table can be found on [crates.io](https://crates.io/crates/tracing-tracy) and the version used can be found [here](https://github.com/bevyengine/bevy/blob/latest/crates/bevy_log/Cargo.toml).
 
+On macOS, Tracy can be installed through Homebrew by running `brew install tracy`, and the GUI client can be launched by running `tracy`.

+In one terminal, run:
+`./capture-release -o my_capture.tracy`
+This will sit and wait for a tracy-instrumented application to start, and when it does, it will automatically connect and start capturing.

 The name and location of the Tracy command line tool will vary depending on how you installed it - the default executable names are `capture-release` on Linux, `tracy` on macOS and `capture.exe` on Windows. In one terminal, run this tool: `./capture-release -o my_capture.tracy`. This will sit and wait for a tracy-instrumented application to start, and when it does, it will automatically connect and start capturing.
 
 Then run your application, enabling the `trace_tracy` feature: `cargo run --release --features bevy/trace_tracy`. If you also want to track memory allocations, at the cost of increased runtime overhead, then enable the `trace_tracy_memory` feature instead: `cargo run --release --features bevy/trace_tracy_memory`.
