[IDEA]: Add sponsor notices#130

### The Idea As the development of this module has so far been inspired by my own needs, future maintenance and features will depend entirely on my time, needs, and motivation. Maintaining an open-source module is time-consuming as APIs are changing constantly, and breaking changes happens more often than I would prefer. To be able to continue with active development of the module, some donations are necessary. **If you are a company** or are **using this module for a commercial platform**, please consider providing a monthly amount so that it can be split between myself and the dependencies used by Nessie since we have all spent a massive amount of time on the development of the modules. Todo: - [x] Add sponsor notice to the init command - [x] Add sponsor notice in the README
