allow authors to define an accessible table title

Feature Request

This issue was identified during the Docs accessibility audit on a page containing table-related content.

Audited page:
https://docs.numerique.gouv.fr/docs/0d998bef-1b69-47ce-bd18-83d4d849c734/

BlockNote tables do not currently provide a way for authors to define an accessible table title.

A table title helps users understand the purpose of the table before navigating its content, especially screen reader users.

What did you expect to happen?

Authors should be able to define an accessible table title in the table editing UI.

This title should be exposed in the generated markup, preferably using <caption>.

Example:

<table>
  <caption>Project members</caption>
  <thead>
    <tr>
      <th>Name</th>
      <th>Role</th>
    </tr>
  </thead>
  <tbody>
    <tr>
      <td>Alice</td>
      <td>Designer</td>
    </tr>
  </tbody>
</table>

Alternative implementations could use aria-label or aria-labelledby if is not suitable.

Without an accessible table title, users may need to navigate the table content before understanding what the table is about.

A dedicated table title improves comprehension for screen reader users and helps authors create more accessible structured content.
