Pull Request for Issue #40503 .

Summary of Changes

This is the PR to fix this in 4.4-dev. When installing Joomla on a different database server than localhost, a check is done to ensure that you are really the person having control over the server. This check writes a file to the filesystem and the content is empty. The code called File::write() with the string-literal, which is not valid, since you can't hand over a string-literal by reference. This PR first creates a variable, which then is handed over as the content for File::write().

Testing Instructions

Install Joomla 4.4-dev on a system and don't use localhost as your database server. Alternatively modify installation/src/Helper/DatabaseHelper.php in checkRemoteDbHost() to execute the check even though you are installing to localhost.
