fix(ui): opening relationship field with appearance: "drawer" inside rich text inline block closes drawer (#13830)

Previously, clicking on a relationship with `appearance: 'drawer'`
within a lexical inline block drawer would close both drawers, instead
of opening a new drawer to select the relationship document.

## Technical Notes

The issue happened due to the [`ModalContainer`'s
onClick](https://github.com/faceless-ui/modal/blob/main/src/ModalContainer/index.tsx#L43)
function being triggered when mouseUp on the relationship field is
triggered.

**Causes issue**: MouseDown => drawer opens => mouseUp
**Does not cause issue**: MouseDown => MouseUp => drawer opens

This is why the previous `setTimeout()` fix worked: it delayed the
drawer opening until the mouseUp event occured. If you click very slow,
the issue could still happen though.

I was not able to figure out _why_ the `onClick` of the ModalContainer
is triggered.

## The Fix

This is the ModalProvider `onClick` handler:

```ts
(e: MouseEvent<HTMLElement>) => {
      if (closeOnBlur) closeAllModals();
      if (typeof onClick === 'function') onClick(e);
    },
```

The fix is to simply set `closeOnBlur` to `false`, so that
`closeAllModals` is no longer called.

I was not able to manually trigger the onClick event of the
`ModalProvider`. I figured that it is more often called by strange React
Components triggering events like maniacs (react-select) rather than
some genuine user action.

In case some piece of functionality somehow relied on this event being
triggered and then closing the modal, that piece of functionality could
manually call `closeModal()` or attach a custom `onClick` function to
the modal. That way, this mechanism will be run in a more deliberate,
expected way.
