Fix phpcs issue

Problem/Motivation

The codebase of the Paragraphs Gridstack module currently contains issues reported by PHP CodeSniffer (PHPCS). These issues may include violations of coding standards, stylistic inconsistencies, or other issues that PHPCS has identified. Addressing these issues is essential for maintaining a clean and standardized codebase, improving code readability, and ensuring adherence to coding best practices. Resolving PHPCS issues contributes to a more maintainable and collaborative development environment for the Paragraphs Gridstack module.

Proposed resolution

PHPCS Analysis:
Run PHPCS on the Paragraphs Gridstack module codebase to identify the specific issues that need to be addressed.
Analyze the PHPCS report to understand the nature and extent of the issues.

Prioritize Issues:
Prioritize the identified PHPCS issues based on severity, impact on code quality, and adherence to coding standards.
Focus on critical issues first to improve the overall code quality rapidly.

Create Task List:
Create a detailed task list that enumerates each PHPCS issue to be addressed.
Include information about the files, line numbers, and descriptions of the issues.

Address Issues:
For each identified issue, apply the necessary changes to bring the code into compliance with coding standards.
Ensure that the changes do not introduce new issues and are consistent with the overall codebase.
