Whitespace improperly removed from end of heredoc lines

@prettier/plugin-php v0.18.8
Playground link

Input:

<?php

$foo = <<<EOT
foo   
EOT;

Output:

<?php

$foo = <<<EOT
foo
EOT;

For PHP 7.3 and up, prettier PHP is improperly removing whitespace from the ends of lines in heredoc strings. Note that there are space characters after "foo" in the Input string that are missing in the formatted output. Prettier should not be touching whitespace inside of a string.

This broke an application for us, where we were hashing such strings to generate filenames.

Let me know if you have any questions about this!

Reproduce el caso de heredoc de PHP 7.3+ informado usando el enlace de Playground proporcionado y compara la entrada con la salida formateada. Traza la ruta de formateo de heredoc en el plugin y añade cobertura que demuestre que los espacios finales dentro de las líneas de heredoc se conservan, y confirma que la salida de ejemplo ya no los elimina.
