[ISSUE] Tasklist userAccessRestrictions can not be disabled.

[ingorichtsmeier]

Describe the issue:

Applying the setting tasklist.identity.userAccessRestrictions.enabled: false has no effect.

In the Tasklist, you cannot see tasks with candidate groups where you are not a group member of or not a candidate user.

Actual behavior:
Given values

tasklist:
  enabled: true
  identity:
    userAccessRestrictions:
      enabled: false

the helm chart generate a config map like

    camunda.tasklist:
      identity:
        userAccessRestrictions:
          enabled: "false"

This configuration doesn't match the expected values of Tasklist.

Expected behavior:

The helm chart should generate a config map containing

    camunda: 
      tasklist:
        identity:
          userAccessRestrictionsEnabled: false

This would apply the setting to the IdentityProperties: https://github.com/camunda/tasklist/blob/master/tasklist/common/src/main/java/io/camunda/tasklist/property/IdentityProperties.java#L88-L91

Another available configuration is this environment variable: https://github.com/camunda/tasklist/blob/master/tasklist/webapp/src/main/java/io/camunda/tasklist/webapp/rest/ClientConfig.java#L55-L56

For this, the helm chart should generate

            - name: CAMUNDA_TASKLIST_IDENTITY_USER_ACCESS_RESTRICTIONS_ENABLED
              value: "false"

in the tasklist deployment.

Please align with the Tasklist team, which configuration is their preference.

How to reproduce:

1. create a Camunda 8 cluster from the default values.
2. Create a process containing a user task and enter a value to Candidate groups. The tester should not be a member of the group.
3. Deploy the process model.
4. Start an instance of the process.
5. Open Tasklist
6. You don't see the task.
7. Change the setting of tasklist.identity.userAccessRestrictions.enabled: to false.
8. Apply the update to the cluster
9. You should see your task now.
