Allow users to configure ESLint's problems settings (#9981)

Presently the only available setting under `problems` is
`shortenToSingleLine`, which defaults to `false`.

Example Zed `settings.json` to shorten eslint error squiggles to only
show on the first line of the problem:
```json
{
    "lsp": {
        "eslint": {
            "settings": {
                "problems": {
                    "shortenToSingleLine": true
                }
            }
        }
    }
}
```


Release Notes:

- Added support for configuring ESLint `problems` settings, ie. `{"lsp":
{"eslint": {"settings": {"problems": {"shortenToSingleLine": true}}}}}`
