jobs: enable downloading execution detail files

In cockroachdb#106879 we added a table to the `Advanced Debugging`
tab of the job details page. This table lists out all
the execution detail files that are available for the
given job.

This change is a follow up to add download functionality
to each row in the table. The format of the downloaded
file is determined by the prefix of the filename.

A final change to allow users to generate execution details
will be added in the next follow up.

Informs: cockroachdb#105076
Release note: None
