Unmaintained spark plugin migration

### Describe the Bug

The spark plugin for this broken, [here](https://github.com/joshuaballoch/asdf-spark) is the original repo. I have forked this repo and fixed the issues. Please switch it to my fixed fork of this [here](https://github.com/sudo-black/asdf-spark).

### Steps to Reproduce

try listing the the available version of the spark it fails as well as the installing of any specified version

### Expected Behaviour

the standard asdf commands of list and install should work as expected

### Actual Behaviour

its should list versions and install specified one

### Environment

Start at the spark plugin entry in the asdf-plugins repository and compare its configured source with the fork at sudo-black/asdf-spark. The change is done when the entry points to the fixed fork and the standard asdf commands for listing and installing Spark versions work.
