(fix): explicitly install npm in Dockerfile.full

[spameier]

I got this error when running docker compose up --build -d in a Project that builds from the master branches Dockerfile.full:

 > [spiderfoot 10/32] RUN apt remove -y cmdtest     && apt remove -y yarn     && curl -sS https://dl.yarnpkg.com/debian/pubkey.gpg | apt-key add -     && echo 'deb https://dl.yarnpkg.com/debian/ stable main' |tee /etc/apt/sources.list.d/yarn.list     && apt-get update     && apt-get install yarn -y     && yarn install     && curl -fsSL https://deb.nodesource.com/setup_17.x | bash -     && apt-get install -y nodejs     && npm install -g retire:

44.67 nodejs is already the newest version (18.13.0+dfsg1-1).
44.67 nodejs set to manually installed.
44.67 0 upgraded, 0 newly installed, 0 to remove and 3 not upgraded.
44.67 /bin/sh: 1: npm: not found

The build fails during the last command (npm install -g retire). Installing npm through apt solves the problem.
