not root user in vscode remote container extension about deno_docker

[hayd]

I thought the base image examples I had seen used system users... but maybe this is not the case?
e.g. https://github.com/nodejs/docker-node/blob/8b68fca7a5089bd8795ae85b55617314e966487b/16/alpine3.11/Dockerfile#L6

1993 is the year Jurassic Park was released 😳

Happy to take PR for alpine dockerfile to fix.

so it looks like i was running into two issues:

• deno is created as an system user -S
• the assigned gid and uid were not mapping to my host and getting permission errors

i altered the base image to below to play nice with the remote container vscode extension:

RUN addgroup deno \
  && adduser --disabled-password deno --ingroup deno\
  && mkdir /deno-dir/ \
  && chown deno:deno /deno-dir/

i do still have a couple questions though. why are the uid/gid set to 1993 and why the -S system user flag? is it a security thing?
