Trying to auth in lynx and fail.

**Describe the bug**

When lynx or www-browser executable pointing to lynx is available, az login will use it instead of falling back to device code, but the auth page will say lynx doesn't support javascript and jump to Microsoft homepage.

This is a recent (~months) regression.
Same script and workflow worked fine in docker for a long time.

If the website doesn't work for certain browser, maybe have a blacklist for it.

**Environment summary**

Bash on Ubuntu 18.04.6 docker running on CentOS 7 host.
