Description:

Before being updated to load custom scripts on #7095, it was only possible to load pre-made scripts from a (now deprecated) repository (github/hubot-scripts), so in the description of the interface, the user is guided to insert names of scripts containing in this repository.

When searching for the variable of the description, we can see that it is still pointing to the repository in a lot of languages and if the user doesn't figure out he has to load the scripts by himself, he won't be able to load scripts at all.
