Dataset's dictionary not updated if one changes the collection dynamically

[Alvant]

• Create a dataset
• Call dataset.get_dictionary()
• Change dataset's _data by renaming one of modalities (eg. lemmatized -> new_lemmatized)
• Try to build a topic model using the dataset

Result: old modality in model's Phi
Expected: new modality in Phi

P.S.
One should also check that dataset._modalities is up-to-date

See? Exactly - if you change the _ variables or methods we don't guarantee proper functionality. You should know what you are doing when using those

[Alvant]

Well... yees... Ok. Then it should be clearly stated in the docstring that currently Dataset provides no way to modify the contents of a text collection (changing document/renaming document/adding modality/...). If you want to change something — use text editors, pandas, csv or something else.
