Docs Limit Keywords To 5

Issue

The pyproject docs make the following claim about keywords:

A list of keywords (max: 5) that the package is related to. Optional

- https://python-poetry.org/docs/pyproject/#keywords

From my testing, this limit is not actually enforced in any way, and I'm not quite sure why it exists. I've asked on the discord server here, and didn't get a conclusive answer.

I deployed this package with 7 keywords from this pyproject.

At no point did anything complain, and all 7 tags show up fine on the pypi page. (For reference, the linked package is converting an already existing package from using setuptools to poetry. The main package has the same 7 tags with no problem.)

I traced this change back to a commit (e907f40) that added a bunch of documentation, and I can't see a clear reason behind the limit.

Looking the code, indeed it seems that there is no limit enforced by poetry. PEP 314 also did not constraint the keywords to any specific limit. https://www.python.org/dev/peps/pep-0314/#keywords-optional
I would suggest removing the limit from the doc.

The readme.md also mentions that keywords are up to 5. I made the PR to remove it. #4635
