bug: some random output when entering distrobox while using fish shell

[RealVishy]

Describe the bug

I'm getting some random output about starfish when i enter a distrobox while having my shell set to fish.

Probably an issue with the fish container detection logic that was merged way back, might have to look into it again.

What did you expect to happen?

no stuff about starfish when you make a new distrobox

I think everything that is not installed in the container but referenced in your host's fish config fails. I don't know how to prevent this. On my machine I use direnv from brew and everytime I enter a distrobox I get:

I think the only way to avoid this is to use a custom home dir for your distrobox.

I did that in this distrobox here and it uses the distrobox's config.fish instead of trying to source everything from your user's config.fish.
