0.9.0 official release!

[vobu]

After 4+ release candidates, the final 0.9.0 is out!
No scope changes or feature additions, but work under the hood.

🏎️ improved performance by ~15% for retrieving a UI5 control from browser- to Node.js-scope
🧹 cleaned up transition between Node- and browser-scope
⏱️ introduced internal metrics for measuring performance for code changes → these can also be used in regular tests as described in https://js-soft.github.io/wdi5/#/usage?id=test-performanceresponsiveness
🚚 auto-build docker images for every release: https://github.com/orgs/js-soft/packages?repo_name=wdi5

With these in place, we felt it was time to drop the -rc* suffix and release 0.9.0!
