Global Install fails in node:lts container

I'm trying to install in a `node:lts` docker image and get the following error.

```
# npm install -g pwsh
/home/node/.npm-global/bin/pwsh -> /home/node/.npm-global/lib/node_modules/pwsh/bin/pwsh

> pwsh@0.3.0 postinstall /home/node/.npm-global/lib/node_modules/pwsh
> node ./npm_lifecycle_postinstall.js

Error: EACCES: permission denied, mkdir '/home/node/.npm-global/lib/node_modules/@cspotcode'
```

Dockefile looks like this following [these](https://github.com/nodejs/docker-node/blob/main/docs/BestPractices.md#global-npm-dependencies) instructions for global installs.

```dockerfile
FROM node:lts

ENV NPM_CONFIG_PREFIX=/home/node/.npm-global
ENV PATH=$PATH:/home/node/.npm-global/bin

RUN npm install -g pwsh
```
