Docs: Remove markdown from the DocBlock summary for `WP_List_Table::get_primary_column()`, introduced in [34166].

The PHP inline documentation standards for [https://make.wordpress.org/core/handbook/best-practices/inline-documentation-standards/php/#summary-formerly-short-description summaries] call for not using an markup or markdown. Also, using the full Class::method() in this context allows for better clarity in what is being referenced.

See #33854. See #32246.
