Small description FreqTableSheet open-row created sheet doesn't load links

Expected result Links would be loaded.

Actual result with screenshot https://asciinema.org/a/DyJoj2OPxS57yHaKlxeyvWgO7

FileNotFoundError: [Errno 2] No such file or directory: 'technology-diffusion-paper-final-datasets'

Steps to reproduce with sample data and a .vd

Note this is an issue with 'Enter'/open-row. It looks like links on a sheet created by 'gEnter'/dive-row works.

vd https://www.cgdev.org/technology-diffusion-paper-final-datasets

Hit 'F' to get to the FreqTableSheet. Hit Enter to open-row, now you are on a new ZipSheet. Hit Enter, get the stack trace for FileNotFoundError. The data doesn't load properly.

Additional context Please include the version of VisiData. Latest version of develop.

Not sure if this is already a known error. The GitHub actions are only running test_commands, which is failing on addcol-sh. The Cmdlog tests are not being run.

Thanks, @frosencrantz! This is very helpful. Should be fixed now.
