@ethersproject/random not working properly in service worker

[Elinia]

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:

ethers.js/packages/random/src.ts/browser-random.ts

Lines 12 to 23 in 73a46ef

	let anyGlobal: any = null;
	try {
	anyGlobal = (window as any);
	if (anyGlobal == null) { throw new Error("try next"); }
	} catch (error) {
	try {
	anyGlobal = (global as any);
	if (anyGlobal == null) { throw new Error("try next"); }
	} catch (error) {
	anyGlobal = { };
	}
	}

Hope I'm understanding the error correctly.

Reproduction steps

Environment:

This is quite possible. I'll schedule this fix for the next release. :)

This should be fixed in 5.5.3. Can you try it out and let me know if you still have any problems?

Thanks! :)

Happy to hear that! I'll get the time to try the new version out about next Tuesday.
