fix: trigger onError callback when loading google pay js failed

[shirly-chen-awx]

Background: https://pay.google.com/gp/p/js/pay.js will be failed to load in china if the user don't have the agent software. It's better to call the onError callback when loading js errored.

@JlUgia the build failed, can you help check with that?

[shirly-chen-awx]

Hi, @socsieng can you help check with failed build? It seems it was broken several months ago.

Looks like it's failing here: https://github.com/google-pay/google-pay-button/runs/6650864917?check_suite_focus=true#step:7:22

Checking formatting...
[warn] examples/react/src/serviceWorker.ts
[warn] Code style issues found in the above file(s). Forgot to run Prettier?

Working locally for me, but might be worth running npm run pretty to reformat all files.

Created https://github.com/google-pay/google-pay-button/pull/143 to fix the prettier issue.
