fix(python): refresh the interpreter page after recreating an environment, pick a conda env's Python version

Creating an environment at the path the project interpreter already pointed to (a deleted .venv recreated) left the Python Interpreter page saying "<path> does not exist": the package list and the validity check only reloaded when the path changed. Both now reload after an environment is created.

A new conda environment offered a "Base interpreter" chosen among existing environments, which read as copying one; only its Python version was used. It now asks for a Python version (conda create -p <location> python=<version>), and the note says the environment starts with only Python.
