URL to publications gets "%20" added to the end of the hyperlink.

**Describe the bug** For some reason, the template breaks/adds unnecessary characters to the publication URLs. **To Reproduce** All my publications that have a URL to Arxiv: ```yaml --- title: "Example" collection: publications category: manuscripts permalink: /publication/my-publication excerpt: 'test.' date: 2025-12-03 venue: 'ArXiV' paperurl: "https://arxiv.org/abs/2512.04142" --- ``` When you click on the generated URL hyperlink in the page: <img width="1136" height="324" alt="Image" src="https://github.com/user-attachments/assets/83cb9d3b-e305-48aa-8146-3848cfc6dc65" /> It takes you to the defined URL + %20 (i.e., https://arxiv.org/abs/2512.04142%20) In a URL, %20 represents a space character. For some reason, the "%20" is appended to all arXiv URLs on my publications page, which breaks the URL. **Expected behavior** The URL works as expected and is used as passed.
