dependency-check-core 8.4.0 is no longer supported

[kevin-secops-lt]

Describe the bug

Builds will start failing due to the plugin sbt-dependency-check --> pointing to an old version of the dependency-check-core 8.4.0 I believe.

Version of sbt-dependency-check used

addSbtPlugin("net.vonbuchholtz" % "sbt-dependency-check" % "5.1.0")

Log file

When reporting errors, 99% of the time log file output is required. Please post the log file as a gist and provide a link in the new issue.

To Reproduce

Steps to reproduce the behavior:

1. sbt dependencyCheck

Expected behavior

it should run correctly but it outputs this error:

java.lang.NullPointerException: Cannot invoke "String.toUpperCase()" because the return value of "org.owasp.dependencycheck.utils.SeverityUtil.unscoredToSeveritytext(String)" is null at templates/htmlReport.vsl[line 795, column 43][0m 12:47:32 [0m[[0m[31merror[0m] [0m[0m([31mdependencyCheck[0m) org.apache.velocity.exception.MethodInvocationException: Invocation of method 'getHighestSeverityText' in class org.owasp.dependencycheck.dependency.Vulnerability threw exception java.lang.NullPointerException: Cannot invoke "String.toUpperCase()" because the return value of "org.owasp.dependencycheck.utils.SeverityUtil.unscoredToSeveritytext(String)" is null at templates/htmlReport.vsl[line 795, column 43][0m

I'm sure this is because of this issue here: https://github.com/jeremylong/DependencyCheck/issues/7191
