The `flavorTemplate` has been introduced in `ProjectSettingsState` to allow developers to customize the i18n string replacement format. In addition, the `LocalizeItAction` class has been simplified by refactoring commented details into JavaDocs and adding methods to replace selected text and build replacement strings. A new utility class, `DocumentUtil`, checks the document type during string replacement.
A new setting, `flavorTemplate` is introduced to specify how strings are replaced with i18n representation. This includes code modifications for handling this new feature and also updates in the messages.properties file for the associated UI text. The feature is especially useful for customizing how localization strings are generated in different project setups.
