Fix: Loose Comparisons in ms-functions.php

[debarghyabanerjee]

While going through the ms-functions.php file, I found that loose comparisons are used in several instances.

Trac Ticket: Core-62283

## Overview

• This pull request addresses the use of loose comparisons in the ms-functions.php file. Loose comparisons can lead to unexpected behavior and potential bugs, so this update replaces them with strict comparisons for improved reliability and clarity.

## Changes Made

• Identified and updated all instances of loose comparisons to use strict comparisons ( === and !== ).

• Ensured that any necessary type checks are handled appropriately to maintain the intended functionality of the code.

## Benefits

• Enhances code reliability by preventing unexpected type coercion.

• Improves code readability and maintainability by following best practices for comparison.

## Testing

• Conducted tests to ensure that all functionality remains intact after the changes.

• Verified that no new issues were introduced during the refactoring process.
