Add extraction support to react-i18next framework

This commit adds the `supportAutoExtraction` array of supported formats
and the `detectHardStrings` method from `GeneralFramework` to enable
hard-coded string extraction for react-i18next framework, without
needing the "general" framework to be enabled/loaded in the
`.vscode/settings.json` file.
