Improve test reliability

[mbien]

tests are still failing too often. Since we don't have CI stats for github, I tried to crawl workflow results using a rudimentary bash script calling into the github API.

The script scans workflow runs and filters merges to master which failed, then scans re-runs too and prints the failed steps. Rest is just sort and uniq.

     14 "ide/project.ant" - done
     13 "java.hints batch1"
     11 "java.file.launcher" - done
     10 "ide/css.editor"
      7 "groovy/groovy.editor" - done
      6 "webcommon/html.knockout"
      3 "platform/o.n.bootstrap"
      2 "java/maven"
      2 "java.hints batch2"
      1 "web.beans"
      1 "platform/openide.nodes"
      1 "java.editor"

note: this does not take the retry script into account which might be active on some steps

here the results with the links pointing directly to the workflow run:

I take java/maven and will try platform/o.n.bootstrap

[mbien]

i take a look at ide/project.ant

(testGetBuildScriptState: org.netbeans.spi.project.support.ant.GeneratedFilesHelperTest)

edit: found the issue - turns out it was a real bug: #8190

[mbien]

for groovy/groovy.editor -> #8191

[mbien]

for java.file.launcher -> #8193

[mbien]

extracted java.hints batch1 failures into separate issue since this might be a real bug/be more difficult to fix -> #8195
