chore(model gallery): update deepseek-r1 prompt template

[M0Rf30]

Description

This PR fixes deepseek-r1 prompt. </think> splitting is missing, I already tried with cutstrings parameter but seems that regex doesn't work.

Notes for Reviewers
This is the entire jinja template

# {% if not add_generation_prompt is defined %}
