feat: enable the language definitions to be auto-updated on settings change

- Added new `updateLanguageDefinitions` function in Configuration class to update the language definitions.

- Refactored the `onDidChangeConfiguration` event in the `activate` function of the extension to auto-update the language definitions and reconfigure the comment blocks when a user changes the settings. It uses the new `updateLanguageDefinitions` function to update the definitions before reconfiguring the comment blocks.

- Removed the old `reloadRequiredSettings` array and the `showReloadMessage` function.
