Internal `ServiceConfigurationError` when Script Engine is created

[jpsacha]

When javax.script.ScriptEngineManager is attempting to list available script engines, numerous ServiceConfigurationError are internally generated resulting in printouts to standard error output that look like:

ScriptEngineManager providers.next(): javax.script.ScriptEngineFactory: Provider org.scijava.plugins.scripting.scala.ScalaScriptLanguage could not be instantiated
ScriptEngineManager providers.next(): javax.script.ScriptEngineFactory: Provider dotty.tools.repl.ScriptEngine$Factory could not be instantiated

While the code still works and test are passing this is producing confusing printouts and slows down the execution of the scripts, tests are running about twice as long as without that issue.

The issue was introduced after META-INF/services/javax.script.ScriptEngineFactory was added #1.
