The main change in this PR fixes the snapshot functionality in the Publish pane-related components. Because the code cell outputs are now rendered in their own iframes for security reasons, a single snapshot of the notebook is no longer possible: each cell output takes its own snapshot and the snapshots are collated on the main notebook snapshot.
- Move the snapshot functionality to notebook components: this removes the reference of the notebook DOM node that we must pass to the Publish pane via explorer.
- Add slice in the state and actions in notebook redux for notebook snapshot requests and result
- Add post robot message to take snapshots and receive results
- Add logic in `NotebookRenderer` to wait for all output snapshots done before taking the main one collating.
- Use `zustand` to share snapshot between Redux world and React world. This solves the issue of keeping the `PanelContainer` component generic, while being able to update its children (`PublishPanel` component) with the new snapshot.
Additional changes:
- Add `local()` in `@font-face` to check if font is already installed before downloading the font (must be done for Safari, but not Edge/Chrome)
- Add "Export output to image" menu item in notebook cell, since each cell output can take its own snapshot (which can be downloaded)

We have a custom implementation of `Markdown` cell that we use in `NotebookRenderer`. This custom implementation disables HTML rendering in markdown cells. This change uses the same for `NotebookReadOnlyRenderer` which we use for Gallery.
This change enables notebooks to escape HTML (which is a vector for malicious attacks).
We import `MarkdownCell` from the `@nteract/stateful-components` sources so that we can point it to the version of `@nteract/markdown` which contains [this fix](e19c7cc590).
This is a temporary workaround from upgrading to `@nteract/stateful-components` to `7.0.0` which causes build and runtime issues see #599).
This fixes a bug that prevents getting focus to a text cell (effectively preventing editing) when the window height is small after double-clicking on a neighboring code cell.
The issue is that selecting a text cell is broken likely because there's a behavior change in MonacoEditor that keeps the focus on the code cell. The selection issue will probably be resolved when migrating the text cell to Monaco (which will acquire and keep focus the same way), but for now, this will disable the faulty code which doesn't appear to work anymore (presumably auto-scrolling to the cell).
