Use param-based badge

[MichaelCurrin]

Make sure to not encode it to keep URL readable

https://img.shields.io/static/v1?label=GH%20Pages&message=MichaelCurrin.github.io/coding-blog/&color=green

But convert space to %20.

See if a flag on the frontend makes sense.

Also the badge can be used on the Repo page to make a repo badge around social section.
