TypeError in Apache action

[belal-i]

Lampsible will fail when trying to set up a bare bones Apache server.

Steps to reproduce:

lampsible user@example.com apache --insecure-no-ssl

Current behavior:

Traceback (most recent call last):
  File "/home/anon/.venv/bin/lampsible", line 8, in <module>
    sys.exit(cli.main())
             ^^^^^^^^^^
  File "/home/anon/.venv/lib/python3.12/site-packages/lampsible/cli.py", line 596, in main
    lampsible.run()
  File "/home/anon/.venv/lib/python3.12/site-packages/lampsible/lampsible.py", line 621, in run
    self._update_env()
  File "/home/anon/.venv/lib/python3.12/site-packages/lampsible/lampsible.py", line 413, in _update_env
    value = [
            ^
TypeError: can only concatenate list (not "NoneType") to list

Expected behavior:

Lampsible should successfully run, and Apache should be running on the host.

Affected versions: >= 2.2.0
