Release notes for v11

[alvarlagerlof]

Expected Behavior

Major versions have releases and release notes in https://github.com/contentful/contentful.js/releases

Actual Behavior

No releases notes (as far as I can find) for v11, which makes upgrading hard.

Preparing them right now, for now, here is my draft for the release notes:

• No internal logic was changed. If you get the new imports working, all your other code should be able to stay untouched.
• We now provide real ESM by default, while also providing CJS variants for older environments
  • This was tested in 22 browsers/devices, AngularJS, GatsbyJS, NextJS, NextJS + TS, Node (with and without TS, with CJS and MJS files), Nuxt, React Native (Expo), Rollup, Svelte, Vite, Vite + TS, Webpack
  • To support all these environments, we define our package type in package.json via the "type": "module" with the regular main field and as well support the new exports field.
• We no more provide pre bundles code for nodejs (removes eval from our exported code)
• Improved tree shaking support (finally)
• Reduced browser bundles sizes almost by factor 3 (128kb -> 45kb)
• Reworked our internal test environment from jest to vitest
