wordpress.org unused variable removed.

[upadalavipul]

I have reviewed the wordpress.org code and found some of the unused variables which are not used anywhere on the below files. So code cleanup purposes we will need to remove it.

Files:

• wordpress.org/public_html/wp-content/plugins/photo-directory/inc/search.php
• wordpress.org/public_html/wp-content/plugins/photo-directory/vendor/google/grpc-gcp/cloudprober/grpc_gpc_prober/spanner_probes.php
• wordpress.org/public_html/wp-content/plugins/plugin-directory/class-template.php
• wordpress.org/public_html/wp-content/plugins/plugin-directory/class-tools.php
• wordpress.org/public_html/wp-content/plugins/theme-directory/rest-api/class-theme-review-stats.php

Why would we need to remove these variables?

Sorry, but these changes are extremely minor and inconsequential. They don't affect the performance, security, readability, or functionality of the code or the sites that use them. These may eventually get addressed when surrounding code gets changed or amended in the future, but until then, effort is better spent elsewhere.
