Docs: Parameter '$plugin_editable_files' type is not compatible with declaration

[subrataemfluence]

The parameter $plugin_editable_files accepts an array in the following function but the in Doc block, it has been defined as string, which is incorrect. It has to be declared as an array.

<?php
/**
 * Makes a tree structure for the Plugin Editor's file list.
 *
 * @since 4.9.0
 * @access private
 *
 * @param string $plugin_editable_files List of plugin file paths.
 * ...
 */
function wp_make_plugin_file_tree( $plugin_editable_files ) {
  $tree_list = array();
  foreach ( $plugin_editable_files as $plugin_file ) {
     ...
  }
  return $tree_list;
}

Here is a call made in plugin-editor.php

<?php
$plugin_editable_files = array();
foreach ( $plugin_files as $plugin_file ) {
  ...
  $plugin_editable_files[] = $plugin_file;
}

...
wp_print_plugin_file_tree( wp_make_plugin_file_tree( $plugin_editable_files ) );
...

where $plugin_editable_files is passed as an array.

Docs: Fix the @param type for wp_make_plugin_file_tree().

$plugin_editable_files is an array, not a string.
