@ethersproject/random not working properly in service worker

Describe the bug

I’m using ethers.js on a wallet (chrome-extension) project.

Everything worked well in when testing in web pages. But when I move the code to background.js (run as a service worker), it starts to complain about “no secure random source avaialble” (<-- a typo here!).

Actually I solved this issue in my project by adding following code into the beginning of the service worker code:

self.global = { crypto: self.crypto };

So I believe we can be avoid of this issue by adding another condition here:

https://github.com/ethers-io/ethers.js/blob/73a46efea32c3f9a4833ed77896a216e3d3752a0/packages/random/src.ts/browser-random.ts#L12-L23

Hope I’m understanding the error correctly.

Reproduction steps Run any code that uses randomBytes in @ethersproject/random under service worker environment.

This is quite possible. I’ll schedule this fix for the next release. 😃
