feat: optionally exclude descriptions from tag search results

No description provided.

Can you describe the added value in this feature? What is wrong with just doing as described here after getting the results if you are only interested in the tag?
#87

Also, this PR leaves the search method with two potental output formats: The original list[tuple[str, str]] and the new list[str]. I am not too keen on that since it can be confusing and can lead to issues. But I am open to being convinced otherwise.

I agree with the proposal in #87 , and actually never want the description when searching for tags. So for me the value is that I do not have to implement the proposed scrubbing in all other applications :)

For the second point, I thought that the need to specify an optional input value would alert the user that the output format is different.

ODBC is no longer relevant so I think this is good to go
