chore: Bump jest to v30

[teogeb]

Async dispose

Upgrade caused multiple errors about missing [Symbol.asyncDispose]() in npm run check:

  ../../node_modules/typescript/lib/lib.esnext.disposable.d.ts:40:5
    [Symbol.asyncDispose](): PromiseLike<void>;
           ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    '[Symbol.asyncDispose]' is declared here.

test/unit/PushPipeline.test.ts:108:15 - error TS2345: Argument of type 'PushPipeline<StreamMessage, StreamMessage>' is not assignable to parameter of type 'IPushBuffer<Error | StreamMessage, Error | StreamMessage>'.
  Property '[Symbol.asyncDispose]' is missing in type 'PushPipeline<StreamMessage, StreamMessage>' but required in type 'AsyncGenerator<Error | StreamMessage, any, any>'.

Not sure how esnext types are used (the sdk uses es2021 in tsconfig.jest.json).

Added simple implementations of [Symbol.asyncDispose]() to PushBuffer and PipeLine. That solved the issue.

Bucket test

Changed Bucket to throw TypeError instead of generic Error. Now functionality matches what we assert in the Bucket.test.ts.

Future improvements

Add tests for the [Symbol.asyncDispose]() implementations (i.e. the correct cleanup actually happens)
