If network offline or API error happens, the `session` returned by the `useSession` hook will be null, so we can't assume it is not null.
There should be following changes:
1. create a page in ErrorBoundary to let the user refetch the session.
2. The `SessionProvider` stop to pull the new session once the session is null, we need to figure out a way to pull the new session when the network is back or the user click the refetch button.

This pull request adds a feature to the frontend component of AFFiNE that allows the user to share a page in either `page` or `edgeless` mode, which affects the appearance and functionality of the page. It also adds the necessary GraphQL operations, types, and schema to support this feature in the backend, and updates the tests and the storybook stories accordingly.
* Modify the `useIsSharedPage` hook to accept an optional `shareMode` argument and use the `getWorkspacePublicPagesQuery`, `publishPageMutation`, and `revokePublicPageMutation` from `@affine/graphql`
