• Bug fix (non-breaking change which fixes an issue)

Description

Fixes whitespaces in Development Environment names. Adds validation in the create_dev_env() function in create_cmd.py. If a name with whitespace is provided, an error message is displayed, and the creation is aborted. Added test function in test_create_cmd.py to make sure that the function does not proceed to retrieve an existing Development Environment if the name contains whitespace. It also tests if the error message is displayed.

How Has This Been Tested?

Tested locally. Passed all unit tests in test_create_cmd.py before test_create_dev_env_with_whitespace() was added and passed all tests after.
