As dev, I'd like to test the behavior of att_amend_desc() when using and updating config, so that I make sure it will return an error in this case.

Client validation

• [x] a test exists to catch the error when att_amend_desc(use.config = TRUE, update.config = TRUE)

=> https://github.com/ThinkR-open/attachment/blob/main/tests/testthat/test-amend-description.R

Tech

• [x] Add a test in test-amend-description.R
