Synchronize AssemblyScript versions between packages

Description

Environment

• @graphprotocol/graph-cli v0.97.1, which uses assemblyscript v0.19.23
• @graphprotocol/graph-ts v0.38.1, which uses assemblyscript v0.27.31

Problem

keywords: assemblyscript, equality, string checks, string comparison, null check, ==, ===, !=, !==

In previous versions of graph-ts, we were able to perform null checks using ==. But now, in the latest versions, we are forced to use === (otherwise, we get all sorts of errors at build time).

I wouldn't have a problem with using ===, but we are also forced to use == for string comparisons.

This is a super error-prone design where the maintainers have to remember to use slightly different operators for different types.

Solution

Upgrade to AssemblyScript v0.20, in which the === operator no longer checks for strict object equality.

@graphprotocol/graph-cli と @graphprotocol/graph-ts の AssemblyScript 依存関係の宣言を比較し、まず各パッケージのパッケージメタデータとビルド設定を確認します。必要な AssemblyScript のアップグレードが両方のパッケージと互換性があることを確認し、null チェックと文字列比較が正常にビルドされることを検証します。両方のパッケージが同期されたバージョンを使用していれば完了です。
