Parse checkboxes in Markdown tables
### Current Workaround
See https://gitlab.com/gitlab-org/gitlab/-/issues/21506#note_262038275 for how to use a combination of HTML and Markdown to achieve checkboxes in a table.
### Description
Currently if you add a simple unsorted list you can add checkboxes to it via `- \[ \] description`, I would love to have the same feature for tables.
### Proposal
```
| Done? | Description | Extra information |
|---|---|---|
| [ ] | Things | Blah blah |
| [ ] | That | Hip Hip |
| [ ] | Need | Wunderfull |
| [ ] | Attention | |
```

## Content Editor
Editing this description using the `Rich text` option currently being developed allows for task lists to be embedded in tables. This can't be accomplished using raw Markdown so the source will render out to HTML.
