docs: clarify PyPI distribution type requirements

[jameslamb]

https://www.pyopensci.org/python-package-guide/tutorials/intro.html#publishing-a-package-to-pypi-conda-forge says pypi.org requires both sdists and wheels.

That isn't true. For example, torch has only wheels.

ref: https://pypi.org/project/torch/#files

This proposes updating that language to refer only to file types that PyPI supports.

Notes for Reviewers

I haven't worked with translation files (.po) before so did a very naive update to those that contained this same text. Please let me know if there's a way I can test those changes.

Pull Request Overview

This PR updates the language around PyPI distribution file requirements to clarify that PyPI supports rather than requires source and wheel files. Translation files for Japanese and Spanish have been updated to match.

• Replaced “PyPI requires” with “PyPI supports” in the English tutorial
• Updated corresponding .po entries in Japanese and Spanish locales
• (Translator testing follow-up may be needed to verify spacing)

• The string literal in the Japanese .po file is missing a leading space before "and", causing "[sdist]and" when concatenated. Add a space (e.g., change to " and [wheel]") or merge it into the previous literal, then rebuild the docs to verify the translation.
