Allow templating COMPONENT_NAME during package create

[Racer159]

Is your feature request related to a problem? Please describe.

When creating reusable importable components it would be useful to have a ###ZARF_COMPONENT_NAME### template / variable that can be used to scope that component properly.

Describe the solution you'd like

• Given I have a zarf.yaml with ###ZARF_COMPONENT_NAME### in a string value
• When I run zarf package create on that package
• Then Zarf will template that value with that component's name

Describe alternatives you've considered

We could do this on deploy time or in another way, but most scoping would be around variables or actions and this would be easier / more declarative to do create-time.

Additional context

This would make things like a reusable S3 bucket component easier to make.
