Resolve/process `.md` links

[D4nte]

Problem

I noticed some links on waku.org were invalid:

md file:

[Learn more about Waku](/docs/index.md)

Link rendered by acid-info:

https://waku.org/docs/index.md

I understand the correct markdown content is:

[Learn more about Waku](/docs/index)

But it seems counter-intuitive and an easy pitfall because when working in MarkDown my editor (or is it only me) expect local path to existing files (ie index.md and not index).

Propose solution

Have the framework automatically remove .md on local paths.

Note

The config.json file expect the .md extensions:

  "navigation": {
    "home": "main.md",
    "fileOrdersInSidenav": [
      "main.md",
      "about.md",
      "platform.md",
      "operator.md",
      "contribute.md"
    ],

The immediate problem of 404 links was addressed by acid-info/waku.org#14 via a manual edit.
