Version 12.0.0

Major

• Updated the eslint-plugin-import peer dependency to ^2.19.0.
• Removed the eslint-plugin-import-order-alphabetical peer dependency to use the new import/order rule sorting options available in eslint-plugin-import@2.19.0.
• Use the strict rule to enforce strict mode in scripts.

Minor

• Setup GitHub Sponsors funding:
  • Added .github/funding.yml to display a sponsor button in GitHub.
  • Added a package.json funding field to enable npm CLI funding features.

Patch

• Updated dependencies.
• Fixed a package.json type field value of commonjs setting parserOptions.sourceType to commonjs, instead of script.
• Remove package-lock.json from ignore files, as it is disabled via .npmrc anyway.
• Test Node.js v13 in CI GitHub Actions.
