Link to non-raw GitHub page, with edit link

[zakame]

Let the pod6 docs link to their non-raw GitHub pages, so visitors can
see and maybe help out on improving some more. And for convenience,
also provide an edit link.

There's probably some more improvement to do on the footer as well; will
further work on separate commits/PRs.

There's still the issue that Github can't render Pod6: github/markup#907

[zakame]

@rafaelschipiura ouch, that's a bit annoying, but not too bad that we can't view the raw pod6. I probably should have made it clear in the original PR text that I mean changing the link to a page with the GitHub amenities, rather than to a direct raw text of the pod6.

OTOH, how can I help getting Pod6 rendering to happen?

This ticket is related to #1212.

For github pod parsing see #167.

@zakame I do think it would be better to link to the decorated Github page instead of the raw text, so I agree with merging this. But it doesn't fix #1212, since that is requesting a link to the composed page.

@rafaelschipiura that's probably splitting hairs since #1212 doesn't explicitly say about linking to a fully composed/rendered page, only that we can get to a page where we can proceed to edit (see further context in #53 (comment).) Either way though, I think the core problem (to fix a link to point somewhere we can proceed to do further action later) is hopefully solved by this PR.

Thanks @AlexDaniel ! 🎉
