Fix error message for call to internal method from root namespace

[bdsl]

I noticed that the error output linked from https://twitter.com/afilina/status/1425841636282671105 is not grammatical.

There are probably several other internal code violations that should be detected - e.g. https://psalm.dev/r/8a680925cf but they can be done separately, and I don't know if it's worth fixing them before I or someone else actually encounters a real case of code that should be internal being onerously called.

I found these snippets:

https://psalm.dev/r/8a680925cf

<?php declare(strict_types = 1);

namespace Vendor1 {
	class Foo
	{
		/**
	 	* @internal
	 	*/
		public int $foo = 42;
	}
}

namespace Vendor2 {
    echo (new \Vendor1\Foo())->foo;
}

Psalm output (using commit cc717f7):

No issues!

If you have time and feel the urge then why not? We don't have any policies like 'must affect N users' or anything like that.

Thanks!

Right, I just mean worth the time for me or anyone else who wants to implement the fix. I might do some point in future, not today. I can report the issue if you think that would be useful in case anyone else wants to implement.

Sure, no pressure. We're all volunteers here, there's no obligations of any sort.
