feat: support updating an action with new versions

[iamjem]

Description

Syntax-wise, this looks the same as actions create, only you need to provide the action id for the --name flag:

$./auth0 actions update --name b448822b-cd98-46f9-badd-7b6ebd9b5381 --script "module.exports = async (event, context) => {console.log("update!");return {};}"

Is the id flag more appropriate than name in this case?

Probably? We were actually thinking about making it so someone could provide the uuid OR name.
