Description of problem:

when adding environment variables in a workbench, user sees the following:

I think it may not be clear the difference between "Add another variable" (i.e., adding more key/value pairs in the same secret/configmap) and "Add more variables" (i.e., different key/value pairs in different secrets/confgimaps).

Two possibilities I can see are:
1. change "Add another variable" to "Add another key/value pair" or similar
2. remove the option of adding multiple key/value pairs in the same secret/configmap

Prerequisites (if any, like setup, operators/versions):

Create a Data science project

Steps to Reproduce

1. go to RHODS Dashboard > Data Science Projects
2. enter your project
3. click on "create workbench" button
4. add key/value pairs environment variables using UI
5. check the difference btw "Add another variable" and "Add more variables" 

Actual results:

possible confusion around the 2 options "Add another variable" and "Add more variables" 

Expected results:

TBD

Reproducibility (Always/Intermittent/Only Once):

Always

Build Details:

tested using local deployment of dashboard. The same changes should be in build v1.19.0-3. I will check
