Remove Mandatory Definition for words

[nprime496]

I am trying to install the repo locally but I stumble upon this error:

RuntimeError: Error while exporting skill "Chiffres 2" in file "4_Numbers/skills/4_Numbers_2.yaml": The French word "téléphones" does not have a definition. Please add it to the mini-dictionary.

Reading the code, I notice that there's a check to ensure that all words have a correspondance in mini-dictionnary:

https://github.com/LibreLingo/LibreLingo/blob/3bb6d4deadc27cf7b762fcf63d7bb07ea0ccaac8/src/librelingo_json_export/dictionary.py#L52C1-L56C1

I do not think that it is necessary as it put too much constraints on course creation. Dictionnary should be added to improve existing courses not be an unavoidable requirement.
