Use the official CycloneDX image for source code scanning

[pashok2398]

The toolkit can not scan JAVA code, getting error:

/bin/sh: line 1: mvn: command not found

The above build errors could be due to:

1. Java version requirement: cdxgen container image bundles Java 23 with maven 3.9 which might be incompatible. Try running cdxgen with the custom JDK11-based image `ghcr.io/cyclonedx/cdxgen-java:v10`.
2. Private dependencies cannot be downloaded: Check if any additional arguments must be passed to maven and set them via MVN_ARGS environment variable.
3. Check if all required environment variables including any maven profile arguments are passed correctly to this tool.

The proposal is to use the official CycloneDX image for source code scanning.
