Initial static text url_for implementation

[dave42w]

Description

This PR starts the process of implementing url_for so that Jinja templates can reference Robyn endpoints by function name rather than path see #996

Summary

This PR adds a url_for that returns a fixed string and a test for this.

Changes are limited to 3 files

• templating.py (define the url_for function and add it to the global Jinja environment)
• template.html (display the output of url_for
• test_get_requests.py (add an assert to check the fixed string)

  I think I've done that. I'm running the tests from a separate clone which I have had to modify to work with Python 3.12.7 (updated dependencies are the only changes)
