[Bug] Empty heredocs/nowdocs lead to Unexpected 'EndOfFile' (P1001) error

[miquelfire]

Describe the bug
I came across this error recently. I used an empty nowdoc to eventually add some SQL code later one (other stuff needed to be done before I wrote it), and after other distractions, when I came back to the code, I saw this error. A php -l file command doesn't report an error with the same code. Only common when someone is going to put in a large string, but outside forces results in them not having the string to put in the heredoc or now doc

To Reproduce
nowdoc

<?php
class Test {
   private string $string = <<<'EOD'
   EOD;
}

heredoc

<?php
class Test {
   private string $string = <<<EOD
   EOD;
}

Expected behavior
There should be no error in this case.

Platform and version
Windows 11
Intelephense 1.12.6

Just after posting, I found the root cause. Just having the end indented is enough to trigger the error:

<?php
   $string = <<<'EOD'
   EOD;

Also, if you found this in a search, this does work:

<?php
   $string = <<<'EOD'

   EOD;
