Please remove hashicorp-s-link-checker from GitHub Marketplace

[HashiCorp's Link Checker](https://github.com/marketplace/actions/hashicorp-s-link-checker) appears **prominently** in the marketplace:

https://github.com/marketplace?query=link%20checker&type=actions

There's no need to list an action on the marketplace unless you're:
* Supporting it
* Looking for more consumers

Anyone can use any public github.com repository as an action source regardless of whether it is published to the marketplace.

> This repository has been archived by the owner on Nov 20, 2023. It is now read-only.

There's no reason to continue advertising archived actions.

I'm filing here because I can't file tickets to read-only repositories...
