fix: 1707 web validator waits for validation forever

[jcpitre]

Summary:

Closes #1707

If there is no timeout on the version endpoint, this PR changes nothing.
Changed the code so it does not generate an exception when the version endpoint is called but times out.
Another problem was that the current version (obtained from the jar files) was discarded if there was a time out calling the version endpoint.

Expected behavior:

Web validator does not hang forever if there is a timeout while calling the version endpoint.
If the timeout happens, the version is still correct in report.html

** Testing tips **

The timeout is intermittent, and probably only occurs when the validator service is brought up.
To test this, you could add a delay in VersionResolver.java, e.g. Thread.sleep(5100) to simulate that the endpoint takes a long time to respond. The delay should be above 5000 ms, since it's the time used for the timeout.

I don't know why this character "Ï" was there.
