runtime(graphql): contribute vim-graphql to Vim core
Contribute the core of my vim-graphql project (ftplugin, indent, syntax)
to the Vim project. This replaces the basic ftplugin support that was
already in the runtime with a more complete set of filetype settings. I
can assume maintainership for all of these files.
I'll continue to maintain the higher-level embedded filetype support
separately (in vim-graphql) for now, because it's fairly complex, but we
can consider integrating that code directly into vim later.
runtime files use the MIT license.
