Added filter for Selected Posts argument

[mehul0810]

Description of the Change

As there was no filter present to manipulate the arguments for selected posts that triggered some conflicts with fetching posts from post type not enabled PolyLang to a post type that has PolyLang enabled. So, adding a filter to let us add some additional arguments to achieve the goal.

How to test the Change

Try adding tax_query using the filter post_finder_selected_posts_args
