Wrong IDE platform prefix

[Undin]

What happened?

Starting with 2023.3.2 IDE launched by RunIdeBase task has the wrong platform prefix, it's always JetBrainsClient.
It happens because this code finds -Didea.platform.prefix=JetBrainsClient param in bin/jetbrains_client.sh file of IDE artifact and it considers JetBrainsClient as IDE platform prefix.

As a result, any checks based on platform prefix, for example, all checks in com.intellij.util.PlatformUtils, work unexpectedly for such IDE instances.

The issue is caused by improper shell script scanning to discover the platform prefix.
This should not happen, as 2022.3 explicitly provides such value through the product-info.json file.
Added proper platform version check.
