chore: upgrade to acorn@8.1.0

[vladjerca]

In version 8.0.3:

Fix a wasteful loop during Parser creation when setting ecmaVersion to "latest".

[vladjerca]

Might relate to #435

On my end at least when using karma-typescript in conjuncition with karma-typescript-es6-transform, my tests would lock.

I found out it was locking here:

karma-typescript/packages/karma-typescript-es6-transform/src/transform.ts

Line 62 in 2275e19

context.js.ast = acorn.parse(context.source, { sourceType: "module", ecmaVersion: "latest" });

This was caused to to an acorn bug which caused the parser to lock when using latest as the ecmaVersion. I've upgraded acorn in all packages and I've tested this locally.
