file_watcher feature cannot find assets folder in workspace

[super-saturn]

Bevy version

v0.15.0 #3f2baf8ec

[Optional] Relevant system information

Observed on both Arch Linux and macOS.

What you did

A basic workspace setup where the actual bevy App launches from a subcrate, like the following Cargo.toml setup:

[workspace]
resolver = "2"
members = [
    "library_a",
    "main_bevy_game",
]

The assets folder for the game resides in the main_bevy_game root. There are no other assets folders in the workspace.
main_bevy_game enables file_watcher feature, and then in main.rs:

    App::new()
        .add_plugins(DefaultPlugins.set(AssetPlugin {
            watch_for_changes_override: Some(true),
            ..Default::default()
        }));

What went wrong

On launch, bevy issues the following warning:

WARN bevy_asset::io::source: Skip creating file watcher because path "assets" does not exist.

Creating a folder at the root of the workspace will suppress this warning, but file changes are not recognized.

Moving the assets folder to the root of the workspace causes a panic:

Failed to create file watcher from path "assets", Error { kind: PathNotFound, paths: ["/Users/notarealuser/workspace/main_bevy_game/assets"] }

(Path altered for privacy)

Additional information

I believe this is from using a raw std::path::PathBuf to test if the assets folder exists whereas in most other cases it gets built out.
I have a quick one-line fix:

bevy_asset crate @ bevy_assets/src/io/source.rs

line 534:
let path = super::file::get_base_path().join(path.clone());

This builds the path as it does in file::FileWatcher::new() and seems to make everything work as expected.

This might not be the appropriate fix, or perhaps my project structure is not as intended. I'm not sure, so I haven't opened a PR for this one line change.
