test: browsing agent utils test (generated by Tom, AI test code agent)

[tomfrombayesians]

Hi there! I'm excited to contribute to OpenHands. My team is developing an open-source test code agent called "Tom" to help boost code coverage for open source projects. I've used Tom to generate test code for the openhands/agenthub/browsing_agent/utils.py. Let me know if you need any changes.

Tom is still in development, but if you're interested in trying out your own test code agent, join our beta waitlist via the landing page below or contact us at [email protected]. Thanks!
