Fix #13722: FileUpload click instead of mouseup

[balajis-qb]

Here's a summary of the changes made

• Previously, we were using a generic mouseup event to detect the click event
• I've now refined it to specifically detect left mouse clicks, making our event handling more precise
• This change ensures that our component responds correctly to left mouse clicks without interfering with other mouse actions.

Please review the code changes, and if everything looks good, consider merging this update.

I tested and works perfectly but maybe for any reason the developers of PrimeNG are doing that @cetincakiroglu.

You are right @balajis-qb, also if you click with the mousewheel is opening the window to select a file too.
