Experiment settings have plain text links

Type: Bug

Found verifying #15635

1. Open settings and search python opt

bug
The python.experiments.optInto and python.experiments.optOutFrom settings both have links that are not actually clickable

The settings likly just need to be rendered as markdown (although it would be better to use a proper link with a title too: [some text](https://github.com/microsoft/vscode-python/wiki/AB-Experiments))
