The Jenkins Pipeline domain specific language uses a capitalization convention that starts the symbol with a lower case letter and then uses upper case letters for each word in the symbol.

The git plugin 4.8.0 release incorrectly used GitUsernamePassword as a symbol. It should be gitUsernamePassword.

Both symbols should be accepted in order to retain compatibility, but the Pipeline Syntax Snippet Generator should offer gitUsernamePassword as the preferred form.
