CpsFlowExecution: rephrase Jenkins Shared Library/JSL (doc book term) to mention Pipeline Groovy library/PGL (plugin term)

@jglick> BTW the terminology in https://www.jenkins.io/doc/book/pipeline/shared-libraries/
is unfortunate. By definition a “library” is “shared”; why else would you create a library?
The plugin itself uses the term Pipeline Groovy library.
