[Block Updates] Handle form submissions using a common class for all forms. #138
Description
Is your enhancement related to a problem? Please describe.
As mentioned in the note in PR #126, PR adds a new class for handling block form submissions, while submissions of all forms added via shortcode or widget are still handled by the existing function, leading to some code duplication.
This issue is created to unify the form submission process and handle it with a single class, reducing code duplication and improving the overall codebase of the plugin.
