Describe the bug

quay.io/devfile/universal-developer-image doesn't persist newly installed SDKMAN versions when a PVC is mounted to /home/user

Che version

7.95

Steps to reproduce

1. use the following devfile.yaml to create a workspace

schemaVersion: 2.2.0
metadata:
  name: home-persistence-test
components:
  - container:
      image:  quay.io/devfile/universal-developer-image:latest
      sourceMapping: /projects
      volumeMounts:
        - name: home-vol
          path: /home/user
    name: tools
  - volume:
      size: 10Gi
    name: home-vol

2. once workspace starts, run the following in a bash terminal to install java 23 and set it to default globally

sdk install java 23.0.2-amzn
sdk default java 23.0.2-amzn

3. afterward if you run java --version you will get openjdk 23.0.2* as expected.
4. run sdk list java, 23.0.2-amzn shows with status installed
5. restart workspace and run java --version you will see it is back to default openjdk 17.0.13*
6. run sdk list java, 23.0.2-amzn doesn't showa as it is installed

Expected behavior

after installing a new version of java and setting it to default using sdkman, restarting workspace should persist the new version

Hello, for quay.io/devfile/universal-developer-image, the sdkman candidates are stored here:

$ echo $SDKMAN_CANDIDATES_DIR
/home/tooling/.sdkman/candidates

To persist the new version of Java, could you try:

schemaVersion: 2.2.0
metadata:
  name: home-persistence-test
components:
  - container:
      image:  quay.io/devfile/universal-developer-image:latest
      sourceMapping: /projects
      volumeMounts:
        - name: candidates
          path: /home/tooling/.sdkman/candidates
    name: tools
  - volume:
      size: 10Gi
    name: candidates

Also, for persistent /home/user, have you considered enabling persistent user home from the CheCluster CR?
