Describe the current behavior

According to the docs, there are currently four top level objects for the Jinja templating in Notifications: flow run flow deployment work queue

Describe the proposed behavior

Adding a top level object for workspace and account to be included in the Jinja templating for the body of notifications

Example Use

Something like this in the templating would be cool: Flow run {{ flow.name }}/{{ flow_run.name }} observed in state {{ flow_run.state.name }} at {{ flow_run.state.timestamp }} from {{workspace.slug_name}}

We do currently support account and workspace objects in the notification templates. Looks like we just need to update the documentation here.
