feat: update acorn for dynamic import

[DRoet]

might resolve parts of #8656 ?

What kind of change does this PR introduce?
Acorn merged dynamic imports in version 6.2.0, so the need for acorn-dynamic-import is no longer needed.

Did you add tests for your changes?
No, but I ran all the tests which include import()

Does this PR introduce a breaking change?
No, I don't believe so

What needs to be documented once your changes are merged?
...nothing ? I'm no expert on acorn so feel free to close this issue if im way off
