CompatHelper: bump compat for "GLPK" to "0.14"

[github-actions]

This pull request changes the compat entry for the GLPK package from 0.13 to 0.13, 0.14.

This keeps the compat entries for earlier versions.

Note: I have not tested your package with this new compat entry. It is your responsibility to make sure that your package tests pass before you merge this pull request.
