CompatHelper: bump compat for Turing to 0.38 for package ppl, (keep existing compat)

[github-actions]

This pull request changes the compat entry for the Turing package from 0.24, 0.25 - 0.29, 0.30 to 0.24, 0.25 - 0.29, 0.30, 0.38 for package ppl.
This keeps the compat entries for earlier versions.
