Describe the bug

If you import something from @graphql-tools/utils in your TypeScript project, and you are using a fixed `lib' in your tsconfig.json (e.g. es2024), you get the following type errors when you run typescript:

node_modules/@graphql-tools/utils/typings/executor.d.ts:8:159 - error TS2304: Cannot find name 'Disposable'.

8 export type DisposableSyncExecutor<TBaseContext = Record<string, any>, TBaseExtensions = Record<string, any>> = SyncExecutor<TBaseContext, TBaseExtensions> & Disposable;
                                                                                                                                                                ~~~~~~~~~~

node_modules/@graphql-tools/utils/typings/executor.d.ts:9:161 - error TS2304: Cannot find name 'AsyncDisposable'.

                                                                                                                                                                  ~~~~~~~~~~~~~~~


Found 2 errors in the same file, starting at: node_modules/@graphql-tools/utils/typings/executor.d.ts:8

The issue can be worked around in two ways

• use "lib": "esnext" (or add esnext.disposable) in your tsconfig.json
• set skipLibCheck to false in your tsconfig.json

To Reproduce Steps to reproduce the behavior:

https://stackblitz.com/edit/graphql-tools-ts-lib-issue

Open a terminal and type "npm run build" (the default dev script does not run typescript)

Expected behavior

The package can be used in an app without skipLibCheck: true and with a regular lib version (like es2023 or es2024).

Environment:

• OS:
• @graphql-tools/...: 10.8.0 or higher
• NodeJS:

Additional context

The issue has been introduced in this PR: #6921

The Explicit resource management, where the Disposable and AsyncDisposable types come from, is currently in phase 3 and has not been released in a ecmascript version. Therefore, it's still only part of "esnext" in typescript. I think a lib should not force an app to enable experimental typescript features, so I would expect the lib to work with one of the released versions. Also, the breaking change has been introduced in a minor version - requiring new typescript lib features should be considered a breaking change and only done in major versions.

To prevent issues like this, it might be beneficial to set an explicit lib' version in the tsconfig.json` of this repo and communicate that as required for dependents.

While skipLibCheck: true removes the error, this is not a good solution because it ignores all type problems in all libraries used by an app, and replaces problematic silently with any.
