Add option to use ./ before relative paths

[EternityForest]

Is your feature request related to a problem? Please describe. VS code previews, and I assume many other apps, see most links as broken.

Describe the solution you'd like An option to prefix all paths that are relative to the file's directory with ./

Describe alternatives you've considered I'm not sure there are any, due to limitations of existing tools.

I suggest a config option. E.g., markdown_internal_link_prefix. It will default to "", but you can modify it to "./". Will that work for you?
