sdl2, sdl2-*, libsndfiles: Install and uninstall scripts fail to (un)register `PKG_CONFIG_PATH` and `CMAKE_PREFIX_PATH` (script error)

[HaSa1002]

Bug Report

Package Name: sdl2, sdl2-image, sdl2-mixer, sdl2-ttf, libsndfile

Current Behaviour

The install and uninstall scripts don't register the PKG_CONFIG_PATH and CMAKE_PREFIX_PATH and instead fail to execute:

$pcdir = $(current_dir $dir)\lib\pkgconfig
$cmdir = $(current_dir $dir)

It throws a command not found error because current_dir is not a command.

Expected Behaviour

It should register both paths to the environment variables.

Possible Solution

I replaced $(current_dir $dir) with $dir and it works just fine.

Note, this also applies to these scripts:

ScoopInstaller/Extras/bucket/libsndfile.json
  18,25:             "$pcdir = \"$(current_dir $dir)\\lib\\pkgconfig\"",
  31,25:             "$pcdir = \"$(current_dir $dir)\\lib\\pkgconfig\"",

ScoopInstaller/Extras/bucket/sdl2-image.json
  48,31:             "$current_dir = \"$(current_dir $dir)\"",
  96,31:             "$current_dir = \"$(current_dir $dir)\"",

ScoopInstaller/Extras/bucket/sdl2-mixer.json
  49,31:             "$current_dir = \"$(current_dir $dir)\"",
  97,31:             "$current_dir = \"$(current_dir $dir)\"",

ScoopInstaller/Extras/bucket/sdl2-ttf.json
  49,31:             "$current_dir = \"$(current_dir $dir)\"",
  97,31:             "$current_dir = \"$(current_dir $dir)\"",

ScoopInstaller/Extras/bucket/sdl2.json
  44,25:             "$pcdir = \"$(current_dir $dir)\\lib\\pkgconfig\"",
  45,25:             "$cmdir = \"$(current_dir $dir)\"",
  60,25:             "$pcdir = \"$(current_dir $dir)\\lib\\pkgconfig\"",
  61,25:             "$cmdir = \"$(current_dir $dir)\"",

I am not sure if that was valid at some point. I can't find any information online about current_dir being a thing. Neither for powershell nor for scoop. However, I don't really write powershell scripts. If I would be a 100% certain this is a bug in the script, I would just pr a fix.
