Improve CI/CD Pipeline

[Highfire1]

Currently, the website takes around 5 minutes to build and deploy from Github - this seems like something that could be improved:

Possible optimization steps:

• yarn install takes ~70 seconds, can we use a caching layer or otherwise reduce the number of dependencies?
• yarn build takes ~50 seconds, are there any ways to optimize the build speed?
• Decrease the size of the final binary which is in the region of THREE GB ??!?!?
  • I believe this is somewhere around 800mb compressed
  • Since we're building on our self-hosted runner that does go towards the monthly 10TB egress limit and probably maxes out our bandwidth while it's uploading.

Further work to be done:

• yarn build should not take 40 seconds
• use docker's officially supported caching layers to save build time on the server
• its possible that the image size could be further optimized

summary of around 4 hours of work:

• npm and yarn do not play nice together and they hate working with docker
• potential speed up is about 2 minutes from a current build time of 6 minutes
