hotfix (dataset): enhance dataset editing and validation

- Modified the TableKeywords component to remove the external_key reset when the type is updated, only resetting the value.
- Updated the DatasetController to pass authorization checks (`can.edit`, `can.delete`) to the edit view.
- Updated the arrayContainsTypes validation rule to improve the error messages for titles and descriptions, clarifying the requirements for main and translated entries.
- Updated the Dataset Edit view to:
  - Remove unused code and comments.
  - Add authorization checks to the save button.
  - Add a release button.
  - Add icons to the save and release buttons.
  - Add a computed property `hasUnsavedChanges` to determine if there are unsaved changes in the form.
