test(deno): wait for stream to start before aborting request

[yusukebe]

After updating to the latest Deno 2.2.9, the CI stopped in the runtime test for Deno:

https://github.com/honojs/hono/actions/runs/14440296335/job/40488744441

Previously, the test was flaky because the delay before aborting the request (10ms) was too short. This change ensures we wait until the stream has actually started before sending the abort signal.

This PR should fix the CI problems.

The author should do the following, if applicable

• Add tests
• Run tests
• bun run format:fix && bun run lint:fix to format the code
• Add TSDoc/JSDoc to document the code
