Use specifiedBy instead of specifiedByUrl

[Code-Hex]

• I followed as "[RFC] Custom Scalar Specification URLs".
• @specifiedBy directive uses "specifiedBy" field on __Type. ref: schema-introspection

type __Type {
  kind: __TypeKind!
  name: String
  description: String
  ...
  # should be non-null for custom SCALAR only, must be null for the others
  specifiedBy: String
}

• But I didn't fix IntrospectionOptions fields because keeping backward compatible.

@IvanGoncharov Could you review please 🙇

[IvanGoncharov]

@Code-Hex Thanks for reporting this issue 👍
It's issue with spec during review process for "[RFC] Custom Scalar Specification URLs" we change directive from @specified(by: "") to @specifiedBy(url: "") but forget to update introspeciton field.
Introspection field should be specifiedByURL to be consistent with deprecatedReason representing @deprecated(reason: "") directive.
graphql/graphql-spec#649 is still Stage3 and changes are not released yet so we should fix it in a spec.

If you are interested, can you please prepare PR against spec and I will help to fast-track it?

@IvanGoncharov Thanks for reply!
Oh, I'm interested for this fix!
I will send PR to graphql/graphql-spec that I suggest to replace specifiedBy with specifiedByURL following deprecatedReason 👍

Updated: I have sent PR: graphql/graphql-spec#848 🙇
