Apollo VS Code Extension used in server not detecting schema across multiple files

**Intended outcome:**

I am trying to configure the Apollo VS Code Extension to detect and provide checking on a local schema in a server.

Based on a number of attempts using the docs (https://www.apollographql.com/docs/devtools/apollo-config/#server-projects) and other issues in this repo I still cannot get the schema to be detected.

The `apollo.config.js` defined in the project root. Only the server exists in the project.

```
module.exports = {
includes: [__dirname + "/schema/*.graphql"],
service: {
localSchemaFile: "./schema/schema.graphql",
},
};
```

**Actual outcome:**

There is no change in the `schema.graphql`. I cannot access jump to definition, error checking and highlighting, etc.

**How to reproduce the issue:**

I am using a schema split across multiple `.graphql` using imports such as

```
# import User, RegisterUserInput from "user.graphql"
```
at the top of the file.

I also use graphql-codegen to generate the types of the schema for Typescript type assertion in the src. It has not problems.

**Versions**

Extension `1.16.2`

When I try to use the CLI (`apollo@2.28.2`) I get this error
```
› Error: No graph (i.e. service) found to link to Apollo Graph Manager.
› In order to run this command, please provide a graph ID using the 'apollo.config.js' file.
›
›
› For more information on configuring the Apollo CLI, please go to
› https://go.apollo.dev/t/config
error Command failed with exit code 2.
```

Start with the project-root apollo.config.js and the schema/*.graphql files using the reported multi-file import setup. Reproduce with Apollo VS Code Extension 1.16.2 and Apollo CLI 2.28.2, then trace the extension's schema-loading entry point; done means schema detection, jump to definition, error checking, and highlighting work across the split files.
