[JENKINS-52053] Jenkins stash failed after npm install

During my build process, I run NPM install among other tools, before stashing the contents of the working directory for later stages. However, we've noticed that when NPM install is used, the stash at the end of this stage throws a Java I/O exception, saying that the archive contains unclosed entries. Disabling the NPM install stops this issue from occurring. The I/O exception is shown below:

Beginne damit, den Stash-Fehler anhand des Stacktraces durch StashManager.stash, StashStep$Execution.run, hudson.FilePath.archive und TarArchiver.close zu verfolgen. Reproduziere eine Pipeline, die vor dem Stashing npm install ausführt, und vergleiche sie mit einem Lauf, bei dem npm install ausgelassen wird. Als erledigt gilt die Aufgabe, wenn der Fall mit npm install ohne die unclosed-entries IOException abgeschlossen wird.
