Update Node.js dependencies for project

What does this Merge Request do and why?

I noticed our link checker had a new release with a really useful feature: https://github.com/tcort/markdown-link-check/releases/tag/v3.10.0.

This MR is to mostly take advantage of that. It found some broken anchors. While here:

• Brings markdownlint-cli up to date.
• Migrates to new untamper-my-lockfile template: https://gitlab.com/gitlab-org/frontend/untamper-my-lockfile/-/tree/main/templates.

CC @axil @marcel.amirault @kpaizee @claytoncornell just FYI.
