build(docker): Optimize Docker image layers/caching & bump node to 14.15 (#776)

* refactor(docker): Combine RUN statements to reduce number of image layers

* Add --update && --no-cache to apk add command

* Combine RUN statements in first stage

* Consolidate COPY commands from BUILD_IMAGE

* Add docs & snap to .dockerignore

* Revert first COPY statement in 2nd stage

* Write committag.json in first stage & only do one COPY
Also pin base image Alpine version, and add Docker & GitHub Actions update monitoring via Dependabot

* Bump node to 14.15.4

* Change base image to node:14.15-alpine and remove Dependabot Docker monitoring

* Changes in response to PR comments

* Remove ARG/ENV statements from second build stage
