Issue Description
I can't seem to run Unity 2020.1.1f1. I've installed the unity version through the hub, then created a symlink in /opt/. This worked fine with 2019.* releases. I get the error error: Unity version '2020.1.1f1' not found. Use --trace to view backtrace when trying to run. Below are some extra details:

$ u3d --version
u3d 1.2.3
I have faced a similar issue. After a fresh install on Ubuntu (20.04) it was still reporting as not being installed. When I did a u3d list it would list the installation but without a version.
It looks like the method read_version_from_unity_builtin_extra is not reading a valid version number. When I changed this to return the correct (for me) value u3d launched unity as expected. My ruby skills aren't good enough to correctly read the value from this very large binary file but maybe this helps with diagnosis.
