CU-2exy49p: Make sure the cdb.add_concept really adds a concept or somehow make it clear

As per clickup.

Make sure the cdb.add_concept really adds a concept or somehow make it clear

Function is a bit confusing as it in fact requires the names to be pre-processed before it can be used.

Changed cdb.add_concept to a protected method, and changed all calls to it within MedCAT as appropriate.

I've also added a line of doucmentation pointing to to the helper function medcat.preprocessing.cleaners.prepare_name.

add_concept cannot be made private currently due to it useage. Conversely prepare_name cannot be used in the method as the cdbmaker.config is not accessible.

It might be worth checking with users that they're not using add_concept before this is merged.

Looks good. But we really should be leaving a deprecated method for backwards compatibility.

I've resolved the one change regarding documentation as it was done on a later line.

You can check the addition of the add_concept method and the deprecated tag.

Looks good to me.
