Update client-errors.mdx - Update Happy Eyeballs failure error message name and add a condition (device revocation) (#18245)

* Update client-errors.mdx

The error message is actually:   "CF_HAPPY_EYEBALLS_MITM_FAILURE" 

The Happy Eyeballs error can also be seen when a device is revoked. 

When users run into Happy Eyeball errors, they should also check form the dashboard that the particular device is not revoked.

* Update src/content/docs/cloudflare-one/connections/connect-devices/warp/troubleshooting/client-errors.mdx
