Setting up Intellisense for with localSchemaFile is broken

Having issues getting VSCode extension (apollographql.vscode-apollo) to find my graphql file. Am I missing some configuration?

apollo.config.cjs file:
```
module.exports = {
client: {
service: {
name: "default",
localSchemaFile: './src/schema.graphql'
},
},
};
```

folder structure:
```
- src/
- schema.graphql
- apollo.config.cjs
```

Reproduce the issue with apollo.config.cjs and src/schema.graphql in the VSCode Apollo extension. Start by checking how localSchemaFile is resolved from the configuration, then verify that Intellisense discovers the schema and document the configuration or code change needed to make it work.
