[Enhancement] Synchronized Markdown Navigation

[codymikol]

I plan on implementing this in a fork, please let me know if you agree with this feature and would like to include this in a PR or have feedback on the implementation.

Synchronized Markdown Navigation

Currently when navigating a markdown document, links render as expected.

If you navigate to the link, you will be greeted by a 404, which isn't great

I think in addition to rendering the document within the link, it would be great if upon clicking the link

A ) The browser navigates to the clicked link and renders appropriately
B ) Neovim navigates to the selected document.

This would allow you to intuitively navigate documents within the browser and make adjustments within neovim without also needing to change contexts.
