Use 'registry.devfile.io' by default in Eclipse Che

[ibuziuk]

Is your task related to a problem? Please describe

By default, Eclipse Che should be using devfiles from 'registry.devfile.io' as getting started samples. Operator should not provision and manage dedicated operand in the upstream.
Note, that for downstream Dev Spaces we should continue using internal devfile registry.

Describe the solution you'd like

Acceptance criteria:

• Operator fall back on registry.devfile.io by default
• All devfiles from the registry.devfile.io are correctly displayed on the User Dashboard as 'Getting Started' samples
• Workspaces are started successfully based on the 'Getting Started' samples
• Projects are cloned correctly and visible in the newly created workspaces
  • Use the first 'starterProject' during DevWorkspace creation from devfile.io samples / stacks #22486

Describe alternatives you've considered

N/A

Depends on

• It is not possible to start a terminal when workspace started from a devfile from the registry.devfile.io #22524
• Editor is not started when workspace started from some devfiles from the registry.devfile.io #22525

Additional context

Part of the #20251

is there an airgap plan for this for downstream?
