CompatHelper: bump compat for GradedArrays to 0.7 for package test, (keep existing compat)

[mtfishman]

This pull request changes the compat entry for the GradedArrays package from 0.5 to 0.5, 0.7 for package test.
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.
