Render `data-confirm` modals with `GlModal`
What does this MR do and why?
It removes the feature flag bootstrap_confirmation_modals
now that all the issues under the epic related to rendering data-confirm
modals wit GlModal
instead of browser confirmation are done.
The specs were updated to use accept_gl_confirm
helper that tests GlModal
instead of browser confirmation.
