Fixes https://github.com/NASA-PDS/registry/security/code-scanning/17

To fix the problem, we need to ensure that the Jinja2 environment is created with autoescaping enabled. This can be done by using the select_autoescape function provided by Jinja2, which will automatically enable autoescaping for HTML and XML templates. This change will prevent XSS attacks by escaping any untrusted input rendered in the templates.

We will modify the creation of the Environment object on line 16 to include the autoescape parameter with the select_autoescape function. This change will be made in the file src/pds/registry/utils/treks/product_collection_builder.py.

Suggested fixes powered by Copilot Autofix. Review carefully before merging.
