[FEATURE] Integrate the badge project into TER pages

[alexander-nitsche]

Is your feature request related to a problem? Please describe.
Extension developers are not aware of these TYPO3 specific badges when writing the documentation.

Describe the solution you'd like
Provide a hint like "Add TYPO3 badges to your README" and link it to this badges project on the official TER page of the extension, like https://extensions.typo3.org/extension/warming, or even integrate this project into the TER project. Ensure that the project can handle high traffic.
