Update CommonsPool2ConfigConverterUnitTests.java (#3147)

* Update CommonsPool2ConfigConverterUnitTests.java

Improves the readability of the test. Numeric literals in assertions have been replaced with descriptive constants, improving readability and making the test easier to understand, modify, and debugging efficiency.

* style: apply Maven code formatting
