[Twisted-Python] GitHub Actions parallelism limit increase

[Kyle Altendorf]

Hi All,

Has anyone contacted GitHub to see if they would be willing to increase 
the parallelism limit in Actions?  My understanding is that we maintain 
two CI systems (GitHub Actions and Azure Pipelines) for the sake of more 
parallelism.  While perhaps worthwhile, this doesn't seem fun.  Maybe 
GitHub would be willing to help out.

Cheers,
