Subject: [PATCH] fix(render): transitive shader imports now work consistently
 on web (#19266)

# Objective

- transitive shader imports sometimes fail to load silently and return
Ok
- Fixes #19226

## Solution

- Don't return Ok, return the appropriate error code which will retry
the load later when the dependencies load

## Testing

- `bevy run --example=3d_scene web --open`


Note: this is was theoretically a problem before the hot reloading PR,
but probably extremely unlikely to occur.
