Dead link on Getting Started site

[TheFutonEng]

At the bottom of this page there is a link to the Walkthroughs:

However, this leads to a dead link of: https://docs.zarf.dev/docs/getting-started/walkthroughs

I imagine it's supposed to link to: https://docs.zarf.dev/docs/walkthroughs

This is Rob M btw.

Also adjusted the netlify settings per https://docusaurus.io/docs/deployment#deploying-to-netlify to ensure that trailing slashes are no longer added automagically.

Also this is not a dead link issue though it does present as one. The issue is due to the routing on docusaurus not handling nested paths correctly unless the link is specific to a file (ie [Walkthroughs](./13-walkthroughs.md)) when a trailing slash is added to the url. @YrrepNoj we may need to update all links in the documentation to ensure this is not happening if a user adds a trailing slash (ie https://docs.zarf.dev/docs/getting-started/), but I updated the netlify settings to stop adding them automatically which will fix the flow from zarf.dev install to the getting started page and also updated the way the links are referenced in the getting started page to provide a more stable solution that should be implemented going forward. defenseunicorns/zarf-docs#31
