Description
While setting Priority Class is supported and Priority Class is mapped like
https://github.com/uutils/coreutils/blob/2c0e1b981fdce56bb8cc729dffed702ff0410e8e/src/uu/nice/src/nice.rs#L159-L167
. showing (mapping) current Priority Class is not supported:
https://github.com/uutils/coreutils/blob/2c0e1b981fdce56bb8cc729dffed702ff0410e8e/src/uu/nice/src/nice.rs#L109-L110
It would be better to be compatible with Cygwin's nice command.
Also, nice should show raw Priority Class e.g. instead of value if it is not a mapped class.

Research direction
Start in src/uu/nice/src/nice.rs, especially the current Priority Class display around lines 109-110 and the mapping logic around lines 159-167. Read the referenced Windows SetPriorityClass documentation and compare Cygwin's nice behavior. Done means nice reports the current Windows Priority Class, including the raw value when it has no mapped class.
