fix: ensure audits inspect final config

[yusufhm]

• adds the --include-overridden flag to drush config:get calls

False positives were identified in some cases when running Shipshape; --include-overridden ensures the final config is inspected.

An example is:

$ drush config:get system.performance css
'system.performance:css':
  preprocess: false
  gzip: true

$ drush config:get system.performance js
'system.performance:js':
  preprocess: false
  gzip: true

$ drush config:get --include-overridden system.performance css
'system.performance:css':
  preprocess: 1
  gzip: true

$ drush config:get --include-overridden system.performance js
'system.performance:js':
  preprocess: 1
  gzip: true
