[Docs] Broken links in Welcome page

[senmm]

Describe the issue

I found some broken links.
These pages have broken link to Terraform Scanning.

• https://www.checkov.io/1.Welcome/Quick%20Start.html
• https://www.checkov.io/1.Welcome/Feature%20Descriptions.html

Perhaps I think the broken link is related to PR #2182

Examples

The following pages should have correct links.
Is the link destination to this page?

• checkov/docs/1.Welcome/Quick Start.md

  Line 174 in 9ac972d

  * [Terraform Plans and Third-Party Modules](https://www.checkov.io/4.Integrations/Terraform%20Scanning.html)

• checkov/docs/1.Welcome/Feature Descriptions.md

  Line 26 in 9ac972d

  * [Scan Terraform plan output and 3rd party modules](https://www.checkov.io/4.Integrations/Terraform%20Scanning.html)
