Wrong JS library path when a11y_autocomplete is manually installed

Problem/Motivation

I installed a11y_autocomplete library using git clone, not with npm.
But a11y.autocomplete.js is not attached because in a11y_autocomplete_element.install file is used wrong - absolute - path.

function _a11y_autocomplete_element_find_library(): string {
  $git_clone = DRUPAL_ROOT . '/libraries/a11y_autocomplete/src/a11y.autocomplete.js';
  if (file_exists($git_clone)) {
    return $git_clone;
  }

This works for me:

function _a11y_autocomplete_element_find_library(): string {
  $git_clone = DRUPAL_ROOT . '/libraries/a11y_autocomplete/src/a11y.autocomplete.js';
  if (file_exists($git_clone)) {
    return base_path() . 'libraries/a11y_autocomplete/src/a11y.autocomplete.js';
  }
