Port from obsolete wsl crate to is-wsl (#9356)

The "wsl" crate was last touched in 2019, whereas the "is-wsl" crate was
last updated in 2023. Additionally, it is unclear whether the "wsl"
crate supports both WSL1 and WSL2 (which was announced in 2019), whereas
the "is-wsl" crate explicitly supports both WSL1 and WSL2.

The required code changes are minimal, since both crates provide only a
`is_wsl() -> bool` function.
