Update nushell.txt to fit nushell

[hackers267]

Change the def-env to def --env to fit the nushell v8.8, because the def-env is deprecated and be removed in v8.8

Fixes #630

This is not related to the PR, right?

[hackers267]

Yes, modify this just because some error in CI

Thanks!

is there a chance there can be a new release of zoxide for this before mid december ?
Just asking since this will become a hard deprecation in nushell around that time (most likely).
We can always work around this of course if you are busy.
Thank you for making zoxide!

[ajeetdsouza]

Can be done! :)

Sorry this took so long to merge, I've been super caught up with work of late.

[happysalada]

Hey no worries at all !
Thanks again for your work on this !

@ajeetdsouza small bump, the breaking release of nu is about 2 weeks away.

[happysalada]

@ajeetdsouza just a friendly ping in case you have a bit of time this weekend.
I'll probably ping again next week if that's alright with you!

[happysalada]

@ajeetdsouza another friendly ping. The release containing the breaking change in nushell has just been made.
No worries at all if you have work, i dont plan on upgrading my system too soon personally, but when you have a moment, it would be nice.

As a workaround for people ending up here:

When you get an error about def-env not working, replace it by def --env:

zoxide init nushell | str replace --all "def-env" "def --env" | save -f ... that way it works automatically and will continue to work on the next zoxide update :)
