[SPARK-28713][BUILD] Bump checkstyle from 8.14 to 8.23

Fixes a vulnerability from the GitHub Security Advisory Database:

_Moderate severity vulnerability that affects com.puppycrawl.tools:checkstyle_
Checkstyle prior to 8.18 loads external DTDs by default, which can potentially lead to denial of service attacks or the leaking of confidential information.

checkstyle/checkstyle#6474

Affected versions: < 8.18

Ran checkstyle locally.

Closes apache#25432 from Fokko/SPARK-28713.
