Update CNCF Social Media Guidelines to be broader

[caniszczyk]

The CNCF Social Media guidelines were originally created and focused on Twitter but we now use multiple social channels along with CNCF projects... from Twitter/X, LinkedIn, Instagram, Facebook, Mastadon, Bluesky and more!

We should update them to ensure they apply to all social media platforms.

Yes we should update them, but what is the meaning of X, LinkedIn?
