Potential fix for https://github.com/crewAIInc/crewAI/security/code-scanning/23

Instead of checking for a substring with assert "https://example.com" in result, the test should assert the presence of the correct, canonical URL within the relevant context. If the expected output is a navigation message (e.g., "Successfully navigated to https://example.com"), use an equality or startswith/endswith assertion, or, if more complex, extract/parse URLs from the output and validate them using urllib.parse to confirm the hostname matches "example.com".

Specifically:

• Change line 174's assertion to check that the URL is present as an exact match, or if the output contains a URL, extract it and confirm its parsed hostname is exactly "example.com".
• Add import for urllib.parse if not yet imported in the test file.
