test: fix Regression/ClientSide/ActionExecution/FrameworkFunctions_NavigateToFunctions_spec.ts (#41015)

## Description
<ins>Problem</ins>

After creating a widget, the page URL was updated. If the widget was
subsequently removed, navigating back from an external site (e.g.,
google.com) caused the app to fail in locating the widget, resulting in
out page selector being unable to open.

<ins>Root cause</ins>

1. Redundant URL assignment persisted after widget deletion, leading to
navigation errors and an inconsistent application state.
2. Additionally, on the fourth spec when we were adding a new action on
the button click, it already had a on click action defined which was
pointing to navigate to google. com and the new navigator we were adding
was getting up and down on top of that. So basically sometimes it was
preferring first navigation and sometimes it was preferring second
navigation.

<ins>Solution</ins>

1. This PR handles the removal of unnecessary URL assignment in the
navigation test, simplifying the test case and improving code clarity
and maintainability.
2. In this PR, we remove the first navigation by applying the onClick
property in a JS mode.
