docs: create Docusaurus v2.3.0 release docs + changelog + release blog post

[slorber]

Motivation

Add 2.3.0 docs version + changelog + blog post + backport all docs changes from commits backported for the 2.2 release

All Docusaurus v2.3.0 links:

• code backport PR
• docs backport PR
• examples PR

---

Preview links:

• https://deploy-preview-8586--docusaurus-2.netlify.app/blog/releases/2.3/
• https://deploy-preview-8586--docusaurus-2.netlify.app/changelog/2.3.0/
• https://deploy-preview-8586--docusaurus-2.netlify.app/docs/2.3.0/

---

The docs have been backported manually, the usual git command I used so far for backports has shortcomings and also we renamed docs from .md to .mdx recently so it doesn't help either 😅

For history, here's a good bunch of commands I tried without success, even trying to tweak patches locally.

git format-patch -k --stdout v2.2.0...slorber/docusaurus-v2.3-backport -- website/docs | sed 's,a/website/docs,a/website/versioned_docs/version-2.3.0,g ; s,b/website/docs,b/website/versioned_docs/version-2.3.0,g' | git apply

echo "abc a/website/docs/xxx/yyy.md" | sed 's,a/website/docs,a/website/versioned_docs/version-2.3.0,g ; s,b/website/docs,b/website/versioned_docs/version-2.3.0,g'
