[MC-250495] Certain IP addresses are not properly censored on the connection error screen

The bug

When attempting to join servers with certain IP addresses, the address is not properly removed from the connection error. This could be problematic, as those who do not want to share the IP address of the server to which they are attempting to connect may accidentally reveal it.

Reported based on the validity of MC-237608.

How to reproduce

Navigate to Multiplayer -> Direct Connect
Enter the IP address 16777216 (or 1.0.0.0 if you'd prefer)
Wait for the connection to time out
❌ The IP address is displayed on the error screen

Unable to replicate on 1.18.2.

Could not reproduce. IP in description is not an IP address.

Hmm, I think you'd also be able to use 1.0.0.0 as an IP address – Minecraft interprets decimal IP addresses properly.
