Don't bundle JS anymore #4955
Description
We no longer need to bundle JS now that deno has improved their caching behavior.
In addition, deno bundle is deprecated and doesn't work with npm specifiers, and is the reason we're stuck with 1.28.2.
On top of that, deno bundle is causing us continued grief with its bugs in cyclic dependencies.
So, let's get rid of it.
I think the main complication is figuring out how to build releases, specifically in macOS, where the notarizer is very particular about directory names. We might need to do a little bit of working around that.
