Earthgames dc682ef120 Print Asset Error with the whole context (#61482)
# Objective

So while using gpui I didn't know that you needed to register a
http_client if you wanted to use images with a link as a source.
So I enabled logs, and I did get errors.
```
20:48:11 [ERROR] Failed to load asset2: error: loading image asset from "https://im.fumo.ing/tLNyIY4n7PEG.jpg"
```
But they didn't tell me what was wrong.

## Solution

I change 2 lines to print the whole error with all the context.

```
20:49:09 [ERROR] Failed to load asset2: Other(loading image asset from "https://im.fumo.ing/tLNyIY4n7PEG.jpg"

Caused by:
    No HttpClient available)
```
And now it does tell you why it doesn't work. ✨Amazing✨.

## Testing

Because I did change the traits needed for the AssetLogger I build zed
to check if it didn't break anything. And it build, so it fine I think.

A quick way to test the change in logging is the gpui example
`image_gallery.rs` and commenting the lines 259 & 260
```rust
        #[cfg(not(target_family = "wasm"))]
        {
            let http_client = ReqwestClient::user_agent("gpui example").unwrap();
            cx.set_http_client(Arc::new(http_client));
        }
```
Or change the URI on line 42 to something non existing.
