Settings keys renames (#11948)

refs https://github.com/TryGhost/Ghost/issues/10318

- Adds following renames to settings table keys:
  'default_locale' -> 'lang'
  'active_timezone' -> 'timezone'
  'ghost_head' -> 'codeinjection_head'
  'ghost_foot' -> 'codeinjection_foot'
  'brand.publicationColor' -> 'accent_color'
- The renames are done to match revised naming conventions and naming
exposed through APIs
- Supersedes this revert - 1eeb5a60b8 and #11946
