Boolean env vars broken in Python > 3.12

[oponomarov-tu]

With the boolean env vars defined as following:

spec:
  containers:
    - args:
        - |
          /app/rundeck_exporter.py
      command:
        - /bin/sh
        - -c
      env:
        - name: RUNDECK_SKIP_SSL
          value: "true"
        - name: RUNDECK_PROJECTS_EXECUTIONS
          value: "true"
        - name: RUNDECK_PROJECTS_EXECUTIONS_CACHE
          value: "true"
        - name: RUNDECK_CPU_STATS
          value: "true"
        - name: RUNDECK_MEMORY_STATS
          value: "true"
        - name: RUNDECK_EXPORTER_DEBUG
          value: "false"

Hi @oponomarov-tu.
Thanks for reporting. I've just released a new version (v2.8.3) that fixes this issue.
