client:codegen fails on windows with Error: No operations or fragments found to generate code for

## Problem
After updating `apollo` to 2.34.0, i get an error on windows when generating typescript code:

```
Error: Command failed: apollo client:codegen --localSchemaFile=C:\companyname\__generated__\schema.json,C:\companyname\src\clientSchema.graphql --target=typescript --includes=C:\companyname\src\**\*.graphql --globalTypesFile=./__generated__/globalTypes.ts --suppressDeprecationWarning --excludes=C:\companyname\src\clientSchema.graphql

⚠️ It looks like there are 0 files associated with this Apollo Project. This may be because you don't have any files yet, or your includes/excludes fields are configured incorrectly, andd Apollo can't find your files. For help configuring Apollo projects, see this guide: https://go.apollo.dev/t/config

Error: No operations or fragments found to generate code for.
```

## Solution

Change backslashes to forwardslashes.
```diff
-npx apollo client:codegen --localSchemaFile=C:/company/__generated__/schema.json,C:/company/src/clientSchema.graphql --target=typescript --includes=C:/company/src/**/*.graphql --globalTypesFile=./__generated__/globalTypes.ts --suppressDeprecationWarning --excludes=C:/company/src/clientSchema.graphql;
+npx apollo client:codegen --localSchemaFile=C:\company\__generated__\schema.json,C:\company\src\clientSchema.graphql --target=typescript --includes=C:\company\src\**\*.graphql --globalTypesFile=./__generated__/globalTypes.ts --suppressDeprecationWarning --excludes=C:\company\src\clientSchema.graphql;
```

## Why does this happen?

apollo@2.34.0 uses apollo-language-server@1.26.9 which upgrades glob from ^7.1.3 to ^8.0.0, which has a [breaking change](https://github.com/isaacs/node-glob/issues/467) which makes it use backslashes as escape characters instead of path separators on windows.

A fix would be to normalize the paths to unix-style using the [normalize-path](https://www.npmjs.com/package/normalize-path) package before using glob to find files to transform, but because this package is deprecated i just wanted to document a potential fix for this error.

Start at the apollo client:codegen entry point and trace how --includes and --excludes paths are passed to glob, with the glob 8 Windows behavior described in the issue. Reproduce the command on Windows using the shown schema and GraphQL paths, then verify that operations and fragments are found and TypeScript code is generated.
