Update repo wiki page based on docs

[oumad]

I tested this on my own fork. Whenever files in docs are changed and pushed to the desired branch (currently set to main), the content of docs/* get all pushed to the repo's wiki. Making the wiki page update correctly.

For this to work :
1- The wiki page must be enabled, by creating a first page (Home.md page).
2- Fill in the placeholders for user info and token in wiki.yml for the CI to work properly.

With this we can have a more readable docs in the wiki page of the repo, this can be linked from the website too until we support converting this markdown pages to static pages.

Do these need to be filled out with anything?

[oumad]

Yes they do, for the CI to run, there needs to be the environment variable for the user token secret, kind of like secrets.GITHUB_TOKEN that you have in release.yml workflow.
for the name and email, those are for the commits, so we can see in the wiki where the updates come from. It usually shows as "revisions".

Sorry for getting to this so late. So I need to change those myself? Or can you do it in this PR?

[oumad]

I don't really know which secret to use to access the wiki, so what I did for now is I changed them to these

env:
  USER_TOKEN: ${{ secrets.WIKI_TOKEN }}
  USER_NAME: github-actions[bot]
  USER_EMAIL: github-actions[bot]@users.noreply.github.com

I cannot really use the same GITHUB_TOKEN you use in the other workflows because the wiki is technically a different repository, so the secret for this repository won't work for it as far as I know, so I just put a WIKI_TOKEN.

Now what you need to do for this to work (hopefully if I didn't miss anything):

1. Go to GitHub Settings → Developer Settings → Personal Access Tokens
2. Generate a new token with wiki permissions
3. Add it to your repository's secrets as WIKI_TOKEN
