Typescript 5 support

[darkbasic]

Describe the bug

Typescript 5 has tighter parameter decorator checking with --experimentalDecorators.
That means constructor parameter decorators should allow undefined as the type of key.

To Reproduce

Use the Inject decorator with Typescript 5+:

error TS1239: Unable to resolve signature of parameter decorator when called as an expression.
  Argument of type 'undefined' is not assignable to parameter of type 'string | symbol'.

50     @Inject(Pool) pool: DatabasePool,
        ~~~~~~~~~~~~

Expected behavior

Works with TS5+.

Environment:

• OS: Gentoo Linux ppc64le
• graphql-modules: 2.1.1
• NodeJS: v18.15.0

Thanks @darkbasic !
This was merged and released in graphql-modules@2.1.2. I confirmed it's working with both TS5 and TS4.9
