Remove call to get Python interpreter and version.

By default, the Microsoft Python Language Server already gets an
existing Python interpreter and version from $PATH if the setting is an
empty string or null.

https://github.com/microsoft/python-language-server/blob/838ba78e00173d639bd90f54d8610ec16b4ba3a2/src/LanguageServer/Impl/Implementation/Server.cs#L143

Looking for `python` and launching the interpreter to get the
version on our end is redundant and time-consuming.
