Remove unnecessary array creation for varargs parameters

SonarLint reports:

Arrays should not be created for varargs parameters (squid:S3878)

There's no point in creating an array solely for the purpose of
passing it as a varargs (...) argument; varargs is an array. Simply
pass the elements directly. They will be consolidated into an array
automatically.
