fix: Update `tsconfig.json` with ES2020 as target.
The SDK has been using BigInt for a long time without explicitly having target: "es2020" in the tsconfig.json file. Based on my research, ES2016 did not include BigInt. I suspect that the omission of target in tsconfig.json had resulted in es2020 to be used implicitly.
Also note that Firebase Admin Node sdk uses es2020.
@MarkDuckworth @sofisl Is this considered a breaking change? If so, are we allowed to make this change now?
@milaGGL FYI
In support of new data types, Firestore will need to use BigInt literals followed by n (things like const largeNumber: bigint = 12345678901234567890n;). And this will not work without the change to tsconfig.json.
This can be considered a breaking change, yes. I'd recommend moving up to Node 18 as the library is due to move, see b/397525375. You are safe to do it this year as most other libraries moved to node 18 this year as well.
