Add MkDocs Wiki

[Hamster45105]

I have created a wiki site for Obtainium with Material for MkDocs. At the moment, it is functional and deploys automatically to GitHub pages. I haven't edited much of the actual content, I just copied the wiki on GitHub.

With this code it will be deployed at https://imranr98.github.io/Obtainium, however you could use a custom domain if you wanted to.

There is a demo here: https://hamster45105.github.io/Obtainium/

Setting the site up to be deployed

The site needs to be enabled via GitHub pages. To do this:

1. Wait until the initial run of deploy-docs.yml is complete
2. Go to the repos settings
3. Go to the pages section
4. Set source to Deploy from a branch
5. Set branch to gh-pages
6. Leave folder as /root
7. Click save
8. This will deploy the site

The wiki should probably then be deleted.

This looks pretty good, thanks! But I think it makes sense to put in a separate repo.
I've created an empty one, could you open a PR there instead?
