 * This shortcode displays the count of entries for a specified Gravity Form, with various filtering options.
 *
 * Shortcode Attributes:
 * - id (int): The ID of the Gravity Form.
 * - field_id (int|string): The ID of the field to filter by.
 * - value (mixed): The value to filter the field by. Supports boolean values ('true', 'false') and merge tags.
 * - field_filters (string): A comma-separated list of field filters in the format field_id:operator:value.
 * - field_filters_mode (string): The mode for field filters. Accepts 'all' or 'any'. Default is 'all'.
 * - format (string): The format for the output number. Accepts 'decimal' or 'comma'.
 * - start_date (string): The start date for filtering entries.
 * - end_date (string): The end date for filtering entries.
 * - current_user (bool): Whether to filter entries by the current user.
 * - display_min (int): The minimum number of entries to display.
 * - display_min_alt_text (string): The text to display if the entry count is less than display_min.
 *
 * Example Usage:
 * ```
 * [gform_shortcode_entry_count id="1" field_id="2" value="example" field_filters="3:is:example,4:>5" field_filters_mode="any" format="comma" start_date="2023-01-01" end_date="2023-12-31" current_user="true" display_min="10" display_min_alt_text="Less than 10 entries"]
