Fix title tags per page for SEO #122
Description
We don't have title tags on pages which may be affecting SEO. Ideally each page should have its own title that can be passed from the MDX (or whatever).
I tried adding this to an MDX page <helmet><title>Foo bar</title></helmet> and in this should work via Helmet inheritance but I wasn't able to get it to work.
I suspect it might be an issue with the child relationships between:
layout/index.jslayout/Header-<lang>.js- some MDX page
Since I think both the page and the headers are children of the layout index but I don't know how that Helmet will work with siblings like that.
