Fix GLIBC issue (#1371)

Use Ubuntu 20.04 to build binaries. [Protostar
v0.8.1](BibliothecaDAO/realms-contracts#270)
doesn't have this problem. [Recently, `ubuntu-latest` was updated to use
Ubuntu 22.04.](actions/runner-images#6399)


> You're better off finding a Python built with a lower glibc
requirement which in practice means building on an old version of Linux
or an old docker image.

pyinstaller/pyinstaller#5669

Probably Fixes #1293
