This pull request sets the compat entry for the EnzymeCore package to 0.8 for package DifferentiationInterface.
This keeps the compat entries for earlier versions.

It is your responsibility to make sure that your package tests pass before you merge this pull request.
Note: Consider registering a new release of your package immediately after merging this PR, as downstream packages may depend on this for tests to pass.
