Interpolated string is not a parse time constant #11561
Description
Describe the bug
Attempting to import a string using any primitive (use, source, source-env) reports an error like:
Error: �[31mnu::shell::not_a_constant�[0m
�[31m�[0m Not a constant.
╭─[�[36;1;4m/var/folders/tb/pg24gy7x5nbc5c_v1pv1chy00000gn/T/nushell-82712-y5pRVbCy7aXR�[0m:1:1]
�[2m1�[0m │ use $'any/script.nu'
· �[35;1m ────────┬───────�[0m
· �[35;1m╰── �[35;1mValue is not a parse-time constant�[0m�[0m
╰────
�[36m help: �[0mOnly a subset of expressions are allowed constants during parsing.
Try using the 'const' command or typing the value literally.
Separate issue: this particular error doesn't strip terminal colors in the LSP for some reason.
How to reproduce
use $'any/script.nu'Expected behavior
I expected it to work like `'any' + /script.nu.

I discovered it trying to work around #7849 (another low-hanging fruit) another way 🍒
