conda not detected after install

[TylerLeonhardt-alt]

Testing #18349

On a fresh Ubuntu 20.04 machine, if you install Anaconda, any running instance of VS Code won't recognize that it's been installed.

Steps:

• Start VS Code
• open the terminal and install conda
• the script tells you to reload your terminal so I do
• I then try to configure the interpreter used in the Python extension and it doesn't detect the freshly installed conda

I assume this is because the VS Code process needs fresh environment variables so I need to reload vscode

Workaround:

• reloading vscode properly detects conda

This is expected, if you hit refresh on from the selection quick pick or reload, it should pick up the new environment.
