fix(schema): application hardware database

[eeberhard]

Description

In #405, I added database entries for hardware, but unfortunately didn't check the typescript type generation using this approach. The mutually exclusive conditional requirements lead to unknown properties.

In the original PR I had mentioned two options, and didn't have a strong preference for either so just chose one:

Currently, I have a oneOf condition that requires either urdf (string) or the new database_entry (object) property. I could also have done it so that the single required urdf property is oneOf string or object. Please let me know your preference.

Now I have a strong preference for the second case!
