Make pixi env conda compatible by default about pixi

[pavelzw]

IMO the conda shim is a too hacky fix to be in pixi's default workflow. JetBrains should instead either allow better python plugins (xref https://youtrack.jetbrains.com/issue/PY-63692/Python-local-interpreter-panel-dont-show-third-party-Python-SDK, JetBrains/intellij-community#2591) or have native pixi support themselves.

Pixi itself is already conda compatible (i.e. you can run any conda commands with -p /path/to/.pixi/envs/default).
Adding the shim to a default pixi project also requires python to be available in the pixi project (which is not always the case, so we would need to distinguish this case).

Hopefully this is only a "bridge" solution until there is either the possibility for a proper pixi pycharm plugin (afaik it's not possible yet due to the restricted python sdk, happy to be proven wrong) or native pixi support. Not sure how long JetBrains takes for these things to happen (or how much popularity pixi would need to gain), though.
