[Feature] Hide parts of README.md on the website

[SpaceEnergy]

Before Requesting

• I found no existing issue matching my feature request
• This request is related to Millennium, and not a request for a specific theme/addon

Describe the feature you'd like!

I’d like to suggest a feature that lets you hide certain parts of the README.md from being shown on the theme page.

I want to include something in the README.md that would break the publishing guidelines (see Rule 4), but it should still be visible on GitHub.

With this feature, that content could stay in the file but just not be rendered on the website.

Anything else?

Maybe it could work like this:

<!-- HIDE_ON_MILLENNIUM_BEGIN -->
This part gets hidden on the website.
<!-- HIDE_ON_MILLENNIUM_END -->

Everything between those two comments would be ignored when rendering the theme page.

Could be a clean way to handle stuff that’s not allowed by the rules but still nice to have in the file.
