PyCharm support for DevContainers not working as expected

[undo76]

PyCharm has added support for devcontainers, but for some reason it is not working as expected. Some issues:

• libraries are not recognised in the editor
• There is "Connect" option to "devcontainer", but not "dev"

Maybe related to this? https://youtrack.jetbrains.com/issue/IJPL-65915/DevContainers.-workspaceFolder-variables-localWorkspaceFolder-localWorkspaceFolderBasename-dont-work-for-clone-sources

Update: replacing ${localWorkspaceFolderBasename} with raglite seems to do the trick.

I tested PyCharm's Dev Containers feature on the Conformal Tights repo, and it did work for me. You do need to be careful to:
1. select with Mount Sources, and
2. configure the Python interpreter to the virtual env created under /opt/my-project-env/bin/python.

I created #261 to explain exactly what you need to do to get it to work, and also improve the default experience a bit. Let me know what you think!

Unfortunately, it seems that PyCharm does not yet allow to configure the Python interpeter in devcontainers.json.
