client: rename Execute to Do

583d0b1bcb ("client/graphql: handle GraphQL errors") changed
Execute behavior by wrapping the result into a struct with "data"
and "errors" fields. This is a breaking change, but it's hard to
spot when upgrading core-go because it won't cause a compilation
error.

Rename Execute to Do to break the build and force callers to update
accordingly.
