Increased Page Speed by Switching to ESBuild

Up until now, the react parts of this site were built by Hugo when it built the rest of the site. This was easy and worked great but I ran into limits. I could not trim unneeded stuff from the bundles, and page loads were taking too long. By switching to esbuild, I am able to trim away all the unneeded code, making the page much more efficient.

I also changed how the recipe image is displayed, so it loads sooner and the page should no longer shift as it loads.
