Update phpmyadmin.inc (#4590)

* Update phpmyadmin.inc

The issue with the CSS and JS files not loading may stem from the configuration of the alias directive and how Nginx resolves file paths in a custom template. I changed `root` to `alias` in the CSS and JS location block, as the alias directive is essential for accurately mapping the request URI to the filesystem path.

* Update for debian aswell
