3.0.0.Final - Jakarta EE 9 variant of weld-junit

This new major version switches to EE 9 meaning it supports and uses Weld 4/CDI 3.0 and with it the jakarta namespace.
Otherwise it brings no functional changes over the latest 2.x release.

Note that this also means that anyone who needs to still run on top of older versions/namespaces will have to keep using version 2.x which we now have a branch for and which will keep getting updated as well.

If you find any issues, please report them via GH issues and we'll into them as soon as possible.

Happy testing!
