migrate to @caiyongji/firestore-stripe-payments

This is because this repo using outdated firebase. As no one maintains this project, i've created new one @caiyongji/firestore-stripe-payments.

npm i @caiyongji/firestore-stripe-payments

I've lost at least a day of effort because of the old firebase dependencies breaking my code when updating firebase and then getting errors such as

Error: Component analytics has not been registered yet
    at Provider.initialize (provider.ts:239:13)
    at initializeAnalytics (api.ts:112:47)
    at getAnalytics (api.ts:85:10)
    at firebase-app.ts:32:19```

非常にありがたいです。
ところで、Firebase 11ではエラーが出ます
10.14.1あたりでは動作するようです
