refactor: Update WebhookComponent to use langflow.custom.Component and langflow.inputs.TextInput

The code changes in `Webhook.py` update the `WebhookComponent` class to inherit from `langflow.custom.Component` instead of `langflow.custom.CustomComponent`. It also replaces the `langflow.schema.dotdict` import with `langflow.template.Output` and updates the `build_data` method to use the `self.data` attribute instead of the `data` parameter. Additionally, it adds a new input `TextInput` for providing a JSON payload. This refactor improves the consistency and readability of the code. The commit message follows the established convention of using a prefix to indicate the type of change.
