Autosave oxcfmt only works with .oxfmtrc.jsonc file and not vite.config.ts #959

Describe the bug

When I'm setting the oxcfmt settings in my IDE as per the documentation
https://viteplus.dev/guide/fmt#configuration

So pointing it to vite.config.ts and not the .oxfmtrc.json file. I'm seeing the following output

WARN tokio-rt-worker oxfmt::lsp::server_formatter: Failed to build config resolver: [path]/vite.config.ts
Ensure the file has a valid default export of a JSON-serializable configuration object., falling back to default config

Resulting in the formatter not using the settings provided in vite.configt.ts. When I use a .oxfmtrc.jsonc file instead, and configure my IDE to use that file instead, format on save does work.

I'm currently using Vite+ 0.1.12
