Some callouts inherit from parent callout icon

[mcanouil]

Bug description

Callouts' icon gets inherited following this rule:

• html: Important > Caution > Warning > Tip > Note
• revealjs: Caution > Tip > Warning > Important > Note

It's worst for revealjs than html where top banner can also inherit the colour of the parent.

• typst and latex are fine.

• docx does not support nested callouts. (stack trace not pretty but informative)

• pptx does not support callouts.

Same result for: 1.6, 1.5, and 1.4

Expected behaviour

Parent callout should not matter.

Actual behaviour

Parent matters.

We don't (and will not) support nested callouts, but we should issue error messages
