Support only ESM at first (line#794)

Eventually, we will support both ESM and CJS, but this change will first
support ESM only.
The changes are simple.
1. This changed `import hoge from "./hoge";` to `import hoge from
"./hoge.js";` This is the majority of the changes.
2. This specified in the package.json that it is ESM (`"type":
"module"`).
3. This modified the tsconfig.json for ESM.

Subsequent changes will reintroduce support for CJS. As a result,
line-bot-sdk-nodejs is expected to become a dual package.
