The checkVersionAvailability() in ckeditor5-dev-release-tools does not work on Windows

The checkVersionAvailability() in ckeditor5-dev-release-tools does not work on Windows, because its arguments are wrapped inside ' by shellEscape(). Example command that is generated by this util looks like:

npm show '@ckeditor/ckeditor5-upload'@'43.0.0' version

Then, it is passed down to shelljs as:

npm show "'@ckeditor/ckeditor5-upload'@'43.0.0'" version

which throws an error:

npm error code ENOENT
npm error syscall open
npm error path D:\Projekty\ckeditor5\ckeditor\ckeditor5-upload'@'43.0.0'\package.json
npm error errno -4058
npm error enoent Could not read package.json: Error: ENOENT: no such file or directory, open 'D:\Projekty\ckeditor5\ckeditor\ckeditor5-upload'@'43.0.0'\package.json'
npm error enoent This is related to npm not being able to find a file.
npm error enoent

See https://github.com/ckeditor/ckeditor5-dev/blob/0e35f4972c7c8dfdef8055f9b0dbc0cca46003d1/packages/ckeditor5-dev-release-tools/lib/utils/checkversionavailability.js#L22

It works well on non-Windows environments.

Proposed solution

To make all npm-related commands cross-platform compatible, we could use either npm or pacote packages to fetch the required data from npm registry instead of calling shell command.

To make all npm-related commands

Could we modify only commands that use the registry directly? I mean, npm whoami could remain untouched.

Sure, it should work. Probably only commands with escaped arguments cause problems on Windows.
