Regression
Yes
Missing `localhost` in the `hosts` file configuration could cause the Unity Package Manager server to fail to start
Reproduction steps:
1. Remove/comment out on the host file the line 127.0.0.1 localhost
2. Open Unity Hub and open/create a project
Expected Result: The Project launches
Actual Result: Unity is unable to open the project showing an error that indicates it could not establish a connection with the Unity Package Manager server.
Reproduced: when host file misses the configuration that maps localhost to 127.0.0.1
Workaround: Add to the machine host file the mapping: 127.0.0.1 localhosts
