Fixes: scala for java tests, set fossaAnalyzeResult to N/A

[elaguerta-nr]

Fixes

• In fossa-scala.yml, correct the condition to check for newrelic-java-tests repo
• If fossa-list-targets does not find targets, set fossaAnalyzeResult to "N/A"
  • currently fossaAnalyzeResult has the default value of "Error" for repos without targets. Changing to "N/A" makes the data more clear.
  • this change does not affect whether the workflow passes or fails

Refactors

• In all workflows, move variables for custom properties from step outputs to a job environment variable in order to simplify sharing the values across workflow steps.
• Add descriptor to workflow name, i.e. FOSSA CLI Analysis - Gradle
• standardize grep for error logs to be grep -i error (case insensitive)
