Fix warning on declared config variable that originates from commands (#8891)

Browse source 
# Description

This PR fixes an issue described in #8890 where config variables
declared in command parameters cause the warning `use `let-env config =
...` instead of `let config = ...` to be printed.

# User-Facing Changes
The user is only warned when they define a config variable with a
warning with the type `record`.

# Tests + Formatting

I think this can only be tested manually by first trying to reproduce
#8890.
To test if the warning is still printed when it's supposed to be one can
add `let config = $env.config` to the end of the `config.nu` file.
