CompatHelper: add new compat entry for "Reexport" at version "0.2"

[github-actions]

This pull request sets the compat entry for the Reexport package to 0.2.

This is a brand new compat entry. Previously, you did not have a compat entry for the Reexport package.

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.
