Disable release script from CircleCI

The MetaMask bot is currently failing to publish docs updates, and it is
[blocking our ability to release new
versions](https://github.com/MetaMask/metamask-extension/pull/6765).

While we should pursue a proper fix, I think it's worth disabling in the
meanwhile so this glitch doesn't interfere with our regular release
cadence further.
