EventType doesn't include 'save'

[bdueck-oftr]

Environment

• Extension version(s): [6.1.9]
• Bulma version: [e.g. v0.9.4]
• OS: [OSX 14.1.2]
• Browser: [all ]
• How you are customizing the extension: [no]

Current Behavior
Bulma Calendar EventType doesn't include the 'save' event even though this is documented as a valid event type. This causes ts syntax errors when subscribing to 'save' events (works functionally though).

Current definition:

type EventType = 'show' | 'hide' | 'select' | 'select:start';

Possible Solution
Recommend this be changed to:

type EventType = 'show' | 'hide' | 'select' | 'select:start' | 'save';
