Move gatsby site out of bolt repo

[jesstelford]

Avoids a conflict with graphql packages, but still allows doing a
bolt install & running bolt website:start

Why

The graphql v14 update broke the gatsby website 😞

Gatsby depends on v0.13.x
So there ends up being multiple versions of graphql in node_modules (due to Bolt), which then gives this error:

error Cannot use GraphQLScalarType "JSON" from another module or realm.

Ensure that there is only one instance of "graphql" in the node_modules
directory. If different versions of "graphql" are the dependencies of other
relied on modules, use "resolutions" to ensure only one version is installed.

Duplicate "graphql" modules cannot be used at the same time since different
versions may have different capabilities and behavior. The data from one
version used in the function from another could produce confusing and
spurious results.

Use yarn's resolutions field doesn't work (bolt doesn't support it)
