More create() methods

[martindurant]

We have started adding create() functionality, which bootstraps a project type into a directory from a templace.
Currently supported are ["django", "streamlit", "python_code", "python_library", "JLabExtension"]. Eventually, all project types should be able to create themselves, and have a test in test_roundtrips.

Done ad tested in test_roundtrips:
"django",
"git_repo",
"streamlit",
"python_code",
"python_library",
"JLabExtension",
"IntakeCatalog",
"DataPackage",
"PyScript",
"marimo",
"flask",
"dash",
"panel",
"Golang"
"HuggingFaceRepo"

Part of the problem here, is which cases we should require the tool of choice, and where we can simply write a config file. Of course, the config file by itself can't do anything without the tool, but at least we get the project compliant.
