Add opensource.posit.co Python feed

ADD FEED

Hello! I am requesting to add the Posit Open Source Blog's Python feed to Planet Python. Thanks for considering!

My Name/Blog Name: Posit Open Source Blog

My Blog RSS or ATOM Python specific feed url: https://opensource.posit.co/languages/python/index.xml

I checked the following required validations: (mark all 5 with [x])

1. My feed is valid, I checked using https://validator.w3.org/feed/check.cgi?url=MY_FEED_URL and it is valid!
2. My feed is a Python Specific feed, e.g: I am proposing the filtered tag or categorized feed url
3. I only post content to this feed which is related to the Python language and its components and libraries. Or content that I consider interesting for the Python community.
4. I am aware that once my feed is added it can take a few hours to start being fetched (according to the server update cycle)
5. My feed contains only content in English language.

Thanks in advance for adding my feed to the PythonPlanet! 👍

まず Planet Python のフィード設定を見つけ、既存の Python 固有のフィードがどのように一覧表示されているかを確認します。https://opensource.posit.co/languages/python/index.xml の Posit Open Source Blog フィードを追加し、その後、設定がそのフィードを受け付け、引き続き有効であることを確認します。
