Antora resolves `xref` targets from the module pages root, not the
current file's directory. Bare sibling xrefs like `xref:ideas.adoc[]`
inside `gsoc/2017/index.adoc` looked for `pages/ideas.adoc` instead of
`pages/gsoc/2017/ideas.adoc`.
This commit qualifies all ~45 bare xrefs across 14 GSoC pages (2010–
2018) and 2 Outreachy ideas pages with their full module-relative paths.
Also fixes `nav.adoc` where the 2007 GSoC entry incorrectly pointed to
`gsoc/2008/index.adoc` instead of `gsoc/2007/index.adoc`.

This commit creates a new content repository for the Mentored Projects
Working Group documentation. This allows us to have a single, absolute
source of truth for all things documentation. This convention of using a
repository named "docs" follows an existing convention being used across
several Fedora Docs content repositories across the Fedora-verse.
This content was largely imported from the Mentored Projects WG Tickets
repo, where the tickets and docs were once bundled together into one.
This content will eventually be removed from the Tickets repo.
