TypeSpec support - Add typespec.io files (*.tsp) support

[Artifizer]

1. LOW COMPLEXITY - GTS Specification repository:

• create gts-spec/examples/typespec/vms folder and create several examples there - base VM type (CPU, RAM, name, ID), derived VM types for VMWare, Nutanix, Virtuozzo
• create gts-spec/examples/yaml/ui folder and create several examples there - base UI item and derived types menu item, grid, and instance - ui_itemmenu_itemmy_menu_item
• update gts-spec/README.md and mention YAML and TypeSpec support and examples

2. LOW COMPLEXITY - gts-python :

• add yaml support
• add typespec support

in the code, rename JsonFile -> GtsFile, JsonEntity -> GtsEntity, JsonPathResolver -> GtsPathResolver, etc.

I'd suggest to make a tiny fix to just remap yaml and typespec on read to JSON/JSONSchema, the rest logic should remain the same

3. LOW COMPLEXITY - gts-kit:

• add yaml support in the parser
• add typespec support in the parser

4. HIGH COMPLEXITY - gts-kit:

• add yaml support in the viewer (where we have JSON raw view)
• add typespec support in the viewer (where we have JSON raw view)
