talos/omni authentication issue when running inside wsl

[d3287t328]

Bug Report

Description

During the authentication step with Omni, the cli attempts to run a web browser to the OIDC provider that will look something like https://snip.omni.siderolabs.io/omni/oidc-login/snip

Being a vm/container, the ubuntu image tries to launch w3m which does not display any clickable actions for the user, just a blank full screen in the terminal. The url for the auth can be found by pressing the equals key = and manually opened in another browser but this is by no means obvious and can cause installation delays. A more robust solution would seem to be to check if the request is coming from a container and use a method like curl or something else to complete the auth.

• Platform: windows 11, wsl ubuntu, latest versions.

you can use BROWSER=echo to skip opening a browser
