💡Add groupings of tools in toolbox with headings

[benlammers]

1. Describe a problem.

We use many tools and embed options in our rich text editor and have recently been wanting to provide more organization in the toolbox by adding groupings of tools with a give header. Shown here with a section of "Basic Blocks"

2. Describe the solution you'd like. Mockups are welcome.

Would like to pass in configuration that indicates groupings of tools with a named heading. Similar to how it is done in Notion shown below

3. Are there any alternatives? Currently a rough implementation can be done using CSS selectors and pseudo elements to solve this
