Test reports can be in a new location

[TrevCraw]

Refer to OpenLiberty/liberty-tools-intellij#934 from LTI.

With the recent updates to version 3.5.0 for the Maven Surefire Plugin and Maven Failsafe Plugin, test reports are created in a new location by default.

We need to update the code where we currently hardcode the old location: https://github.com/OpenLiberty/liberty-tools-vscode/blob/main/src/liberty/devCommands.ts#L493

The current proposal is to check both new and old report locations, starting with the new location first.
