Description

You can't use tap plugin add on Windows. You can still add plugins manually.

Fails with npm ENOENT, simply because it's npm.cmd on Windows.

Solution: use cross-spawn instead of Node's built-in spawn.

Reproduction

• Run tap plugin add @tapjs/clock

Environment

which tap
npm ls tap
tap versions
tap config list
tap plugin list
# if using typescript:
npm ls @isaacs/ts-node-temp-fork-for-pr-2009
npm ls typescript
# posix:
uname -a
# windows (in powershell)
"$([Environment]::OSVersion.VersionString) $(('x86', 'x64')[[Environment]::Is64BitOperatingSystem])"

Actually, we don't make the call to spawn ourselves here as it's passed off to foreground-child. This is probably an upstream issue then? or maybe we should be doing a manual check ourselves there.
