[JENKINS-68720] Jenkins Pipeline set environmental variable empty if there already same variable name defined

In pipleline job, when setting a variable like:

environment

{

dc = "20"

}

At the same time, if there is global variable defined 

The problem is, the "dc" variable can not be used (found)  in pipeline shell environment variable. However if variable use uppercase like "DC", it can be used.

Start in the workflow-cps-plugin component and reproduce the reported Pipeline case with a global variable and a local environment variable both named dc. Trace how the shell environment is assembled; done means the local lowercase dc value is available despite the existing global variable.
