Codium is not supported any more

## Problem

All API calls return a `403` with:

```
Your subscription does not support this application. Please contact your administrator.
```

## Steps to reproduce the issue

Run Amazon Q extension in coidum `1.112.0`. Using native vscode is working with the same subscription.

## Expected behavior

Last Friday it was still working.

## System details (run `AWS: About` and/or `Amazon Q: About`)

- OS: Ubuntu 24.04
- Visual Studio Code version: 1.112.0
- AWS Toolkit version: Unknown
- Amazon Q version: 1.112.0

Reproduce the Amazon Q extension failure in Codium 1.112.0 on Ubuntu 24.04 using the reported subscription, then compare the same API calls in native VS Code 1.112.0. Trace the extension's API requests and 403 response; done means Codium works with the subscription without returning the reported error.
