Improve nushell template to gracefully handle no match errors

[marcelarie]

Currently, the __zoxide_z command in nushell throws the following error when no matches are found for a query:

zoxide: no match found
Error: nu::shell::non_zero_exit_code

  × External command had a non-zero exit code
    ╭─[/home/marcel/.config/nushell/external/zoxide.nu:33:8]
 32 │   
 33 │       (zoxide query --exclude $env.PWD -- ...$rest | str trim -r -c "\n")
    ·        ───┬──
    ·           ╰── exited with code 1
 34 │     
    ╰────

when the behavior in any other shell is to only return the result of the zoxide command:

zoxide: no match found

This PR modifies the nushell template to ignore errors and display only the zoxide query command result. The cd command is executed only when a valid path is found.

I am happy to change the formatting if any other is preferred.

I'm already seeing the expected behaviour on Nu 0.98.0 (macOS). On what version are you seeing the error trace?

0.99 after an update, everything is working now. Maybe it was something related to my config 🥲
