GravityView 2.23

This would be a minor version update (2.13.5), except that we renamed many functions. See "Developer Updates" for this release below.

* Added: `{is_starred}` Merge Tag. [Learn more about using `{is_starred}`](https://docs.gravityview.co/article/820-the-isstarred-merge-tag)
* Fixed: Media files uploaded to Dropbox were not properly embedded
* Fixed: JavaScript error when trying to edit entry's creator
* Fixed: Recent Entries widget would cause a fatal error on WP 5.8 or newer
* Fixed: When using Multiple Forms, editing an entry in a joined form now works properly if the "Edit Entry" tab has not been configured
* Fixed: View settings not hiding automatically on page load

__Developer Updates:__

We renamed all instances of `blacklist` to `blocklist` and `whitelist` to `allowlist`. All methods and filters have been deprecated using `apply_filters_deprecated()` and `_deprecated_function()`. [See a complete list of modified methods and filters](https://docs.gravityview.co/article/816-renamed-filters-methods-in-2-14).

* Fixed: View scripts and styles would not load when manually outputting the contents of the `[gravityview]` shortcode

__Developer Updates:__

* Added: `gravityview/shortcode/before-processing` action that runs before the GravityView shortcode is processed
* Added: `gravityview/edit_entry/cancel_onclick` filter to modify the "Back" link `onclick` HTML attribute
- Modified: `/includes/extensions/edit-entry/partials/form-buttons.php` file to add the filter

* Fixed: Edit Entry would not accept zero as a value for a Number field marked as required
* Modified: Refined the capabilities assigned to GravityView support when access is granted using TrustedLogin. Now our support will be able to debug theme-related issues and use the [Code Snippets](https://wordpress.org/plugins/code-snippets/) plugin.
