FileUpload: when multiple files are selected and more than one has errors only only one message is shown

[ajjp]

Describe the bug

When I select more than one file either by opening the file chooser or drag to the drag and drop and if more than one is invalid - wrong type, file size limit exceeded , only one message is shown.

I believe the problem is in the "validate" method that is cleaning the "msgs" array in every file validation:

The code is:
this.msgs = []

And should be:
this.msgs ??= []

I have checked the problem and I did a PR with the solution here: #13399
Now we should wait if PrimeNG Team approve it.
Thanks!
