add json to enable autoupdate with the new agent logic (#759)

* add json to enable autoupdate with the new agent logic

* binary output of the archive https://unix.stackexchange.com/questions/3675/how-can-i-get-a-base64-encoded-shax-on-the-cli

* workaround to allow darwin-arm64 to autoupdate

* parallelize bundle creation and notarization.
This will be helpful if/when we decide to build for darwin-arm64.
For now this is useful because we do not offer a binary for m1 yet,
`runtime.GOARCH` on an m1 machine returns ARM64, so the call for the update file would fail
