This is towards fixing `appsmithctl` into a modern component of the
project. First order of business is to get rid of the `shelljs`
dependency, since we don't really need it that seriously, and since it
does weird stuff with `require()` that we can't use `esbuild` to build
`appsmithctl`.
Further PRs will remove `shelljs` from other commands as well, and then
we'll remove `shelljs` from our dependencies.
