Updates the GH Action and makes a small update to the README to test
changes.
A missing install step for Windows Terminal using Scoop has been added.
The versioning of Super-Linter was also switched to v3 to allow
auto-updates within the v3 series. This can be version-pinned again if a
breaking change comes later. The current updates fix some bugs and bump
the linters utilized.
## Validation Steps Performed
Validation will be shown in the build steps.
Closes#7934
Terminal ships with this dependency embedded, and it is not required that you install it separately. Since the link is broken, let's just remove it entirely.
* [x] fixes#7889
* [x] related to https://github.com/microsoft/terminal/issues/7917#issuecomment-707955335
* [x] I work here
* [x] is a docs update
Additionally, update the markdown linter rules in the wake of #7637, because apparently that was never actually applied to any files, so now the onus is on the first person to touch any of our markdown files.
