feat: ListEmailTemplates for SES v2

[eggplants]

Resolves: #58 / Fixes: #51

In addition, I've set up Dev Container to facilitate development.

Demo

❯ npm run dev

> aws-ses-v2-local@2.7.0 dev
> npm run build:watch && npm run start


> aws-ses-v2-local@2.7.0 build:watch
> npm run build --watch


> aws-ses-v2-local@2.7.0 build
> tsc --project tsconfig.build.json


> aws-ses-v2-local@2.7.0 start
> nodemon ./dist/cli.js

Thank you! I'm happy to approve:

• Adding the list templates endpoint
• Changing the start script to use nodemon, although I'd probably keep npm start (with nodemon) as the recommended path in README

I think I'm less sold on devcontainers after using them a bit more for some other projects. While they're nice for some setup, they can also cause lag/slowness, and pain about port forwarding on different systems. Maybe we can spin that out as a separate PR that we can discuss more there?
