Build fails on dependency check

[brentonrace]

Running ./gradlew build on a clean checkout fails with error:
Unable to download meta file: https://nvd.nist.gov/feeds/json/cve/1.0/nvdcve-1.0-modified.meta; received 404 -- resource not found

This seems to be a problem with the dependencycheck plugin that is fixed from version 5.2.3 onwards, as per this comment on the dependencycheck repo.

I believe this can be fixed simply by updating the org.owasp.dependencycheck plugin version in build.gradle to use the latest version.

After getting past the above, I had to update the following dependencies where the old version was flagged with known vulnerabilities by the dependency check:

  implementation 'com.microsoft.azure:azure-keyvault:1.2.4'
  implementation 'org.apache.httpcomponents:httpclient:4.5.13'
  implementation 'com.fasterxml.jackson.core:jackson-databind:2.10.5.1'
