Distinguish Between Array and Path Series Inputs in Fish Shell

Xshe Version

0.5.1

Current Behavior

Passing arrays in fish shell with xshe defaults to treating them as a path series due to the automatic addition of the --path argument.

Expected Behavior

The shell script should be able to differentiate between an array intended as a series of paths and a regular array. Users should be able to pass a regular array without the script automatically considering it as a path series.

Steps To Reproduce

1. Use xshe to set an environment variable as an array in the fish shell.
2. Observe that the array is treated as a path series rather than a simple array.

❯ echo "XDG_DATA_DIRS   = ['element_1', 'element_2']" | xshe --pipe fish
set -gx --path XDG_DATA_DIRS 'element_1':'element_1'
