Drupal 11 compatibility for computed_field

Hello,
I have created a patch for 3.0.x to make it compatible with Drupal 11.

I don't think there is an upgrade path from v3 according to the module's homepage.

There are some submodules in this module that need core version updated.

erik.erskine → made their first commit to this issue’s fork.

Created a merge request to get version 4.0.x working with D11.

Have not tested version 3.x with D11, so can't comment on the patch in #2.
