Minimal maven version misalligned with quarkus/independent-projects

[rsvoboda]

Description

https://github.com/quarkusio/quarkus/blob/main/build-parent/pom.xml#L62 says <supported-maven-versions>[3.8.2,)</supported-maven-versions>

https://github.com/quarkusio/quarkus/blob/main/independent-projects/parent/pom.xml#L75 says <maven.min.version>3.8.6</maven.min.version>

I think these two should be aligned. For some reason I thought 3.8.6 is the minimal version anyway. CC @aloubyansky
