feat: added playwright capabilities to close_tab action

[Zayadul-huq-afnan]

What does this PR do?

This PR adds playwright capabilities to the "close_tab" action. It also enables, closing tabs using tab title and tab index. If the tab title, or tab index is not provided, the the action will close the last active tab.

This action now takes "playwright" as an optional parameter. If the user provides "true" in the playwright parameter, then playwright will connect through a remote debugging port and perform this action. Otherwise, selenium will perform the action.
