Turn off linting by default in VS Code for Python (devcontainers#449)

* Turn off linting by default in VS Code for Python
Linting is on by default if you specify the paths to any linters, so the previous settings would turn on **all** linters.

Also drop linters that don't see much use.

* Fix tests

* Revert all changes

* Remove paths to under-utilized tools and turn off all linting by default

* Bump the version number
