Gravity Forms Zapier Addon 4.3.0

- Updated the *gform_zapier_request_body* filter to be called within GF_Zapier::get_body so that it can be applied both when processing feeds and responding to API requests.

- Added support for the Gravity Forms Integration App on Zapier v2.0.
- Added an add-on setting to toggle the display of Zapier Feeds in the form settings. On sites with legacy feeds created for the Zapier v1.0 integration, this setting is enabled by default, displaying all the feeds. On sites with no legacy feeds, this setting is off by default so the feeds will not be displayed.
- Fixed compatibility issues in PHP 8.
- Updated the feed settings to restrict editing of feeds created in the Zapier v2.0 integration to Admin Labels and Conditional Logic.
- Updated the add-on to use the Gravity Forms Add-On Framework.

- Added translations for Hebrew, Hindi, Japanese, and Turkish.
- Fixed an issue where the entry and payment dates were being formatted before being sent to Zapier
