The doc on the priorities of different configuration sources contradicts with the source code:

https://github.com/Alluxio/alluxio/blob/a7b33a3c04a9c50264d89d7d78824366cea8b6f4/docs/en/operation/Configuration.md?plain=1#L181-L194

https://github.com/Alluxio/alluxio/blob/a7b33a3c04a9c50264d89d7d78824366cea8b6f4/core/common/src/main/java/alluxio/conf/Source.java#L36-L71

Specifically, doc says path defaults has second lowest priority, while code says it has third highest priority, even higher than configurations set by system properties.

This should be a documentation defect introduced in https://github.com/Alluxio/alluxio/pull/9292
