Fix deleting backups through the UI using forced

[FelipeM525]

Description

In the PR #6580, a new parameter called forced was added to the API deleteBackup; however, these changes were not implemented in the UI; therefore, this PR aims to do so by creating a switch to allow the user to send a request to this API with the forced parameter set to true through the UI.

How Has This Been Tested?

First, I implemented the modifications and set ACS up in a local environment. Subsequently, I used the browser's dev tool to check if the request being sent had the forced parameter set to true when the switch was toggled, which it did. At last, I created a couple of backups and removed them successfully with the new switch toggled on.
