[FIX] website_slides_survey: fix uninstall_hook

When #114353 forward port of #112425 which adds an uninstall_hook was
merged, it was not updated with the API change of #108254, which
replaced the `(cr, registry)` parameters by a sole `(env)` as most if
not all uninstall hooks immediately created an environment anyway.

So this hook has been breaking uninstall on anything on which
`website_slides_survey` depends since it was merged.

Fix the hook to match the new API.
