Feature Request: Set `default` in `java.configuration.runtimes` to the workspace environment variable JAVA_HOME

Currently, the default of the Java extension java.configuration.runtimes is used as the default for No Build Tools, but it would be useful to set it to the environment variable JAVA_HOME which is valid for each workspace. The environment variable here is not the terminal, but process.env.JAVA_HOME, which is referenced by extensions such as

• java.import.gradle.java.home
  Setting > java.jdt.ls.java.home > JAVA_HOME > PATH
• maven.terminal.customEnv
  Setting > JAVA_HOME
• java.jdt.ls.java.home
  Setting > Embedded JRE > JDK_HOME > JAVA_HOME > PATH
• spring-boot.ls.java.home
  Setting > Embedded JRE > JAVA_HOME > PATH
• rsp-ui.rsp.java.home
  Setting > JDK_HOME > JAVA_HOME> Windows Registry > PATH
• salesforcedx-vscode-apex.java.home
  Setting > JDK_HOME > JAVA_HOME> Windows Registry > PATH
• plantuml.java
  Setting > PATH

The goal is to be able to use a different JAVA_HOME for each workspace, independent of the system's JAVA_HOME environment variable. For example:

User settings.json

"java.configuration.runtimes": [
	{
		"name": "JavaSE-17",
		"path": "/path/to/java/17",
		"default": true
	},
	{
		"name": "JavaSE-21",
		"path": "/path/to/java/21",
	}
],

Workspace settings.json (Override default runtime to JavaSE-21)

"java.configuration.runtimes": [
	{
		"name": "JavaSE-21",
		"path": "/path/to/java/21",
		"default": true
	}
],

java.configuration.runtimes is a Red Hat extension, but I am posting it here because I believe it needs to be supported by VSCode itself. It is related to the following issues.
#152806 API: allow an extension to change the environment variables

Beginnen Sie mit der Überprüfung des zugehörigen VS Code API-Issues #152806 sowie der Beispiele für Workspace- und Benutzereinstellungen in diesem Issue. Als erledigt gilt die Feststellung, ob workspace process.env.JAVA_HOME die standardmäßige Java-Laufzeit unabhängig von der Systemumgebung überschreiben kann, wobei dieses Verhalten auf die aufgeführten Java-bezogenen Einstellungen angewendet wird.
