`documentMode: ‘string’` produces types incompatible with strict typescript

Which packages are impacted by your issue?

@graphql-codegen/cli

Describe the bug

I want to prefice this by saying it might be a feature request, depending on how you look at it.

When using @graphql-codegen/cli with preset: ‘client’ and documentMode: ‘string’, the generated class TypedDocumentString is incompatible with the typescript options noImplicitOverride and exactOptionalPropertyChecks.

There is a workaround which is to disable those two rules, but since you cannot (as far as I can tell) create typescript rules specific to certain files, you have to disable the rules for the entire project.
