Bug description:
  [Impact]

  Users are unable to use the "Create synthetic ICC profile" feature of
  DisplayCAL as it crashes if it doesn't find a config file in the
  user's home folder as opposed to making one.

  [Test Case]

  1. Ensure that the ~/.config/DisplayCAL/DisplayCAL-synthprofile.ini file doesn't exist.
  2. Launch DisplayCAL.
  3. Select the "Create synthetic ICC profile" option in the Tools > Advanced menu.

  Expected: No crash

  Actual: Crash (see original bug report below)

  [What could go wrong]

  While the patch in question is tested upstream and known to work in
  later versions, it's completely possible that the patch introduces new
  bugs or just doesn't work at all.

  [Other information]

  The bug in question does not exist in the version already in questing.
  Noble and Plucky need this, and it's too close to Oracular's EOL to
  justify this fix.

  [Original Bug Report]

  ## Steps to reproduce

  1. Ensure that the ~/.config/DisplayCAL/DisplayCAL-synthprofile.ini file doesn't exist.
  2. Launch DisplayCAL.
  3. Select the "Create synthetic ICC profile" option in the Tools > Advanced menu.

  ## Current behavior

  Program errors with the following traceback:

  ```text
  No section: 'Default'

  Traceback (most recent call last):
    File "/usr/lib/python3/dist-packages/DisplayCAL/display_cal.py", line 12273, in synthicc_create_handler
      self.init_synthiccframe()
    File "/usr/lib/python3/dist-packages/DisplayCAL/display_cal.py", line 2393, in init_synthiccframe
      config.initcfg("synthprofile", SynthICCFrame.cfg)
    File "/usr/lib/python3/dist-packages/DisplayCAL/config.py", line 1840, in initcfg
      setcfg("calibration.file", defaults["calibration.file"], cfg=cfg)
    File "/usr/lib/python3/dist-packages/DisplayCAL/config.py", line 2093, in setcfg
      cfg.set(configparser.DEFAULTSECT, name, value)
    File "/usr/lib/python3.12/configparser.py", line 880, in set
      raise NoSectionError(section) from None
  configparser.NoSectionError: No section: 'Default'
  ```

  ## Known workaround

  Manually create the ~/.config/DisplayCAL/DisplayCAL-synthprofile.ini
  file, with the following content:

  ```ini
  [Default]
  ```
