@graphql-codegen/cli

Describe the bug

Function loadSchema should support array of pointers as an argument. The function support this behaviour, but the types are not.

graphql-code-generator/packages/graphql-codegen-cli/src/load.ts

Line 31 in b73ed8f

schemaPointers: UnnormalizedTypeDefPointer,

The same problem in method loadSchema in CodegenContext class. It should be Types.Schema[].

graphql-code-generator/packages/graphql-codegen-cli/src/config.ts

Line 425 in b73ed8f

async loadSchema(pointer: Types.Schema): Promise<GraphQLSchema> {

loadSchema from @graphql-tools/load supports array of pointers too.
