Add SSH discount codes to Sponsors page

### Feature Description

There are a few stores around that feature discount codes for Self-Hosted listeners. It would be great to add these to the Sponsors page for listeners to refer to when needed, but only if they are still active.

It is my understanding that these links are still offering discounts to JB listeners, and are a little different than the typical sponsors. @ironicbadger can you weigh in on this?

For instance,
* [ ] [SSH 35](https://www.jupiterbroadcasting.com/show/self-hosted/35/) describes cloudfree.shop
* [ ] https://www.mylocalbytes.com/ - is there a discount code?
* [ ] any others I'm missing?
