fix: rename tedge config property apt.dpk.options.config to apt.dpkg.options.config

[reubenmiller]

Proposed changes

Rename tedge config property apt.dpk.options.config to apt.dpkg.options.config, so that the dpkg related settings are easier for users to find.

The old value is marked as deprecated so it won't break anyones setup, but it will generate a warning marking that the config item has been renamed.

# old name still works
tedge config set apt.dpk.options.config keepold
