Hard to navigate to the docs page

[StevenLocke]

Describe the problem/challenge you have When trying to navigate to the docs, I get a 404 at carvel.dev/ytt/docs/. It then only offers me the ability to return to the main carvel.dev site or a "page not found support site".

Instead, the correct link for ytt's docs is carvel.dev/ytt/docs/latest

Describe the solution you'd like I'd like a simple redirect from /docs to /docs/latest for all of our tools. I don't think we should need our users to remember "if I want the latest docs I need to explicitly write it." Instead, I think we should make the assumption that not providing a version implies they want the latest docs, and give the user something useable, not a generic "page not found".

Alternatively, I'd like to see a directory of our docs versions if we want to make the assumption that the user doesn't know which version they want.
