ref: 6d0f506eef98a0284f521d89d1714d1ac19a1b17 sr.ht-docs/meta.sr.ht d---------
Link GraphQL schemes

This patch adds links to the GraphQL schemes in the Git repositories to
the graphql.md pages for {git,meta,todo}.sr.ht.  The playground also
contains the schemes, but it is only available for logged-in users.
And the source file makes it easier to jump to specific locations, to
share links and to track changes.
Add initial GraphQL documentation
Add API configuration to installation docs
Add configuration links to all installation pages
Ditch configuration_reference pages

These are superfluous
