Render Block Attribute Panics

terragrunt render no longer crashes on exclude or catalog blocks with certain attributes

Rendering a config crashed with a value has no attribute of that name panic before any output could be produced when:

• the exclude block set no_run, or
• the catalog block set default_template, no_shell, or no_hooks.

These attributes are now carried through the render pipeline alongside the other fields on their respective blocks, so both blocks round-trip cleanly.
