As a User, I can export more information from Test Step Attachments

As a User, I can export more information from Test Step Attachments.

Currently, it is only possible to export these mappings:

Id: ${TestSteps[n].Attachments[l].Id}
Name: ${TestSteps[n].Attachments[l].Name}
Image: ${TestSteps[n].Attachments[l].Attachment}
FileURL: ${TestSteps[n].Attachments[l].FileURL}

It should be possible to export the same mappings as in the issue attachments:
