Report which requested font families are not present on the system (#3006)

This PR improves the error message when `FontCache.load_family` attempts
to load a font that is not present on the system.

I ran into this while trying to run the `storybook` for the first time.
The error message indicated that a font family was not found, but did
not provide any information as to which font family was being loaded.

### Before

```

    Finished dev [unoptimized + debuginfo] target(s) in 8.52s
     Running `/Users/maxdeviant/projects/zed/target/debug/storybook`
thread 'main' panicked at 'called `Result::unwrap()` on an `Err` value: could not find a non-empty font family matching one of the given names', crates/theme/src/theme_settings.rs:132:18
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

```

### After

```
   Compiling storybook v0.1.0 (/Users/maxdeviant/projects/zed/crates/storybook)
