Fix CI with Ubuntu 22.04 about rgbds HOT 3 CLOSED

Actually this may be due to software version differences.

Ubuntu 20.04:

• bison 3.5.1
• make 4.2.1
• cmake 3.28.3
• g++ 9.3.0
• clang 10.0.0, 11.0.0, 12.0.0

Ubuntu 22.04:

• bison 3.8.2
• make 4.3
• cmake 3.28.3
• g++ 11.2.0
• clang 13.0.1, 14.0.0, 15.0.7

I kind of suspect bison, but, I'm using bison 3.8.2 on Xubuntu 22.0.4 and have not had the issues Actions is having.

Evidence that it's a problem with some GitHub Actions update: https://github.com/Rangi42/rgbds/tree/old is also failing, despite being before we converted the RGBASM parser to C++.

Ah, here we go: actions/runner-images#9491
