Fix quarkus.qute.strict-rendering config property name in documentation

[zolv]

A config property name to disable strict rendering of Qute is wrong.
Was: io.lquarkus.qute.strict-rendering - doesn't work,
Should be quarkus.qute.strict-rendering - works just fine.

Thanks for taking the time to create a PR!

I've spent 30mins figuring out why Qute is still using a strict mode. I decided to just try as a dummy, to remove the suspicious io.... part and it worked.
I guess how many people lost their time on that 😄

You should always check the autogenerated configuration reference 😉
