Create a Deploy Now Button Builder

[hunsalz]

Goal Ease the concept of a "Deploy Now button" to everyone. Entering a GitHub Repo URL should generate an image link "Deploy to IONOS" that is shareable all over.

The link syntax is as follows:

https://ionos.space/setup?repo=https://github.com/<GitHub Account>/<GitHub Repo>

The resulting markdown looks like:

[![Deploy to IONOS](https://images.ionos.space/deploy-now-icons/deploy-to-ionos-btn.svg)](https://ionos.space/setup?repo=https://github.com/<GitHub Account>/<GitHub Repo>)
