Fix QuarkusCliTlsCommandIT truststore config property value on Windows

[michalvavrik]

Summary

Here #2036 I fixed the issue for a keystore and didn't realize there is another issue with a truststore. I apologize for doing it on parts, but honestly, spawning Windows machine and setting up environment (or adjusting job) is way more time consuming then just fixing it here. Hope it's alright. Fixes:

[ERROR] io.quarkus.ts.quarkus.cli.tls.surefire.TlsCommandTest.testCommunicationUsingGeneratedCerts -- Time elapsed: 1.479 s <<< ERROR!
java.io.FileNotFoundException: C:UsersnameAppDataLocalTempquarkus-tls-command-tests17294939791165376470 ls-command-testquarkus-qe-cert-truststore.p12 (The filename, directory name, or volume label syntax is incorrect)

If there will be yet another issue after this one, I'll setup an instance.
