Change broken link checker to linkspector

[tuminoid]

User Story

We have GH workflow lint-docs.yml which basically runs a dead link check on the markdown files. Maintainer of that action suggest moving to his new https://github.com/UmbrellaDocs/linkspector as it is using headless chrome to inspect the links. This would be helpful in reducing false positives, as for example GH is responding 404 to simple bots trying to read its website. This leads to false positive issues being created.

This same workflow is trying to be added to metal3-docs where we have many more links and it is riddled with false positives.

Detailed Description

• Broken link checker is migrated to the linkspector.
• Issues related to broken links in CAPM3 and metal3-docs rechecked for validity, new ones to be opened and false positives closed.
