Q CLI login fails to display auth URL when R (r-base) is installed - attempts browser redirect instead

### Checks

- [x] I have searched [github.com/aws/amazon-q-developer-cli/issues](https://github.com/aws/amazon-q-developer-cli/issues?q=) and there are no duplicates of my issue
- [x] I have run `q doctor` in the affected terminal session
- [x] I have run `q restart` and replicated the issue again

### Operating system

Linux (Docker container)

### Expected behaviour

q login should display the authentication URL in the terminal regardless of whether R is installed, allowing users to manually copy and paste the URL into their browser.

### Actual behaviour

With R installed, q login tries to open a browser tab directly instead of showing the URL in the terminal.

### Steps to reproduce

1. Create a Docker container with r-base installed
2. Install Q CLI in the container
3. Run q login
4. Observe that the command tries to open a browser instead of showing the URL

Additional Info:
Minimal reproduction case available via Dockerfile that demonstrates the issue when r-base line is uncommented. Issue identified through testing - Q login works normally until r-base package
is added to the environment.

### Environment

```yaml

```
