Place project-specific settings first in codespell configuration

The `ignore-words-list` and `skip` settings of the codespell configuration file may required project-specific adjustments
to fix false positives or avoid positives from externally maintained files. The other settings are universal. It will be
convenient to have the settings the user might need to adjust at the place of highest visibility in the configuration
file.
