Enable FilesChanged attribute for Workflow component

## Describe your feature request

In the CodeCatalyst console, I am able to filter my workflow triggers by file/directory regex.

## Describe the solution you'd like

When creating my own blueprint using the Typescript libraries, I would like to define this filter programmatically. The FilesChanged attribute for Triggers (described [here](https://alpha.www.docs.aws.a2z.com/codecatalyst/latest/userguide/workflow.top.level.html#triggers-reference)) is currently not available in '@caws-blueprint-component/caws-workflows'.

## Describe alternatives you've considered

There is no programmatic alternative.

## Additional context

Also, the Trigger interface 'TriggerDefiniton' is misspelled in '@caws-blueprint-component/caws-workflows'.

Start in the TypeScript library '@caws-blueprint-component/caws-workflows' and inspect its trigger interfaces, especially the misspelled 'TriggerDefiniton' interface. Done means workflow triggers expose the FilesChanged filter programmatically and the interface name is corrected.
