I added a `.eslintignore` file to my theme as described in the [docs](https://eslint.org/docs/latest/use/configure/ignore#the-eslintignore-file), but I get a warning.

```
[sage] [@roots/bud-eslint] › ⚠ Unknown eslint config format. Please update `.eslintignore` to use one of: js, cjs, mjs, json, yml, yaml
[sage] [@roots/bud-eslint] › ⚠ Unknown eslint config format. Parsed as yml.
```

According to the eslint docs it’s just a normal text file, just like the `.gitignore`.

It’s not blocking for now, but I would like to fix the warning in my project.
