Update chat_template.jinja to correctly parse types nested in arrays

By forcing recursive calls in `render_typescript_type` for "array" types, it now correctly renders any array types that contains items of enum strings or have a "description" field. Before the fix, neither enums nor the "description" field are rendered due to prematurely stopping parsing.
Additionally updated the "any[]" truncation length from 50 to 200, as Enum types typically need longer descriptions.
E.g., these schemas are now correctly rendered:
```
"example_array": {
"items": {
"type": "string",
"description": "An enum string with two types",
"enum": [
"TypeA",
"TypeB"
]
},
"type": "array",
"description": "List of unique enum strings"
}
```
