Bump dependencies

[compulim]

Summary

Bump esbuild@>=0.13.4 to resolve a bug on installing esbuild on npm@>=7 (from node@>=16). And update tests to make sure we can capture similar bugs in the future. Plus, some cosmetics changes.

Design considerations

We want more realistic end-to-end tests. Thus, we are using isolated Docker containers to test every combination of Node.js, NPM, and resolvers.

• Node.js
  • 12, 14, 16
• NPM
  • Default (from current install of Node.js)
  • Latest (run npm install -g npm)
• Resolvers
  • Node.js
    • CommonJS (require('p-defer-es5))
    • ES Module (import 'p-defer-es5')
    • Global object (globalThis.createDeferred)
  • Bundlers
    • ESBuild
    • Rollup
    • Webpack 4 via CommonJS
    • Webpack 4 via ES Module
    • Webpack 5 via CommonJS
    • Webpack 5 via ES Module

Specific changes

• Bumped all dependencies
• Moved terser from production dependencies to development dependencies
  • It is only used in npm run prepublishOnly, which dependents will not run this script
• Segregated end-to-end tests into their own Dockerfile
• Added pull_request_template.md
• Updated scripts/esbuild.mjs for breaking changes from read-pkg-up

Reminders

• I have updated CHANGELOG.md
• I have added tests for new code
• I have updated documentations
