ANW-1548 Unexpected digital object bulk import requirement of DO uri or thumbnail

[brianzelip]

Description

A user noticed that bulk importing digital objects via spreadsheet failed after upgrading from v2.8.1 to v3.2.0 due to an unexpected requirement for a value in either the digital_object_link or thumbnail columns in the bulk_import_DO_template.xlsx file.

The link or thumbnail requirement was added on March 27, 2021 via this commit. (Indeed after v2.8.1 release.)

This PR removes the requirement, essentially resetting the code back to the v2.8.1 state.

It's likely either the case that

• there was an explicit decision to add the requirement, and the instructions in the xlsx file were not updated accordingly, or
• the requirement wasn't an explicit design decision and therefore the instructions weren't updated and the behavior was not seen as a problem until now.

Another PR solution for this ticket would be to keep the requirement and update the instructions to include the requirement.
