Add unhandledrejection & rejectionhandled event support

[Kikobeats]

Hello,

According to CF Workers release, the environment supports unhandledrejection and rejectionhandled events.

I double-check at miniflare code and looks like these events are not supported yet.

Do you think could be easy to add them?

source code related:

miniflare/src/modules/events.ts

Line 114 in e7aee35

this.addEventListener = this.addEventListener.bind(this);

Hey! 👋 The Miniflare 2 pre-release (miniflare@next) includes support for these events.

I understand from #103 (comment) that you're currently using CommonJS imports though. What's your use case, and is there a reason you can't use dynamic await import("miniflare")?

ops sorry, every time I use GitHub to search it doesn't take a look inside branches 😭

I can't use dynamic import because jest has some problem with that and looks like it's actually a v8 thing
nodejs/node#35889

I'm using miniflare to emulate the runtime before ship code to production, and since the issue with jest (and is not possible to move jest out of the project) I'm still stuck at miniflare v1

Have you tried out Jest's experimental ES modules support? https://jestjs.io/docs/ecmascript-modules

unfortunately is hard than that; the project is usingts-jest and is failing using the esm configuration support
