~/.config/fish/conf.d is not created automatically

Problem

When using fish, rustup tries to write to ~/.config/fish/conf.d/rustup.fish, but if conf.d does not exist (but all parent directories do), the installation fails.

error: could not amend shell profile: '/root/.config/fish/conf.d/rustup.fish': could not write rcfile file: '/root/.config/fish/conf.d/rustup.fish': No such file or directory (os error 2)

Steps

1. Ensure that conf.d does not exist in ~/.config/fish
2. Try to install rustup

Possible Solution(s)

Simply check if the directory conf.d exists, and create it if it doesn't

Rustup version

rustup 1.27.0 (bbb9276d2 2024-03-08)
