🚩(frontend) add feature flag on "Copy as HTML"

As a blue print, we add a feature flag on
"Copy as HTML" button in the doc toolbox.
This feature flag is controlled by the `CopyAsHtml`
feature flag.

Be aware:
- if the feature flag is disabled, the button
will be shown
- if the feature flag is enabled and send true,
the button will be shown
- if the feature flag is enabled and send false,
the button will be hidden
