Update Jackson to get rid of deprecation messages

[lppedd]

Thanks for the library!
I'm using it in a custom Gradle task, and every execution I receive deprecation messages from Jackson:

PropertyNamingStrategy.SnakeCaseStrategy is used but it has been deprecated due to risk of deadlock. Consider using PropertyNamingStrategies.SnakeCaseStrategy instead. See FasterXML/jackson-databind#2715 for more details.

It would be cool to update it, or remove usages of deprecated symbols.

If you don't have the time, let me know and I'll do it.

Makes perfect sense. Thank you!
Are you fine with using SNAPSHOT version for some period time or prefer some intermediate minor version?

[lppedd]

@PhantomYdn up to you! What makes less work or more sense (as long as it ends up in Maven Central I guess).

For better context here is the usage: https://github.com/lppedd/kotlin-externals/blob/master/buildSrc/src/main/kotlin/com/github/lppedd/kotlin/gradle/services/NpmService.kt

Thank you for awaiting!

@PhantomYdn thanks! I can confirm it works ok without any deprecation message now.
