Consider not logging warnings when not applicable (for pixi envs)

[DonJayamanne]

I think warning messages are being logged as follows, however this is causing some confusion amongst users.
Suggestion is to turn this into trace or debug, else it could lead to false alarms.

2024-08-01 22:35:26.028 [warning] could not find a pixi interpreter for the interpreter at /Users/pi/code/2024/spins/.venv/bin/python

Like most other users in the issue threads, I also don't know what pixi is and if I should make the effort to install it.

The warning message doesn't help because it doesn't give any info on what pixi is and what a user is required to do. Agree that it's better as a debug message, but in any case, adding some pointers to help the user remedy the issue would help.

In my case, IntelliSense suggestions stop working midway through my session(I reload the window and it's back to normal, before entering the same loop) and I see this warning followed by an ENOENT error in the output stream.
