feat: Add 'source_url' to news articles for original source attributi…

[rishiraj38]

Description This PR adds an optional source_url field to the news article data model. This allows reprinted news articles to properly attribute and link back to the original source.

Changes included:

• Updated src/templates/news-single.js to retrieve source_url from frontmatter.
• Updated src/sections/Company/News-single/index.js to conditionally display an "Originally published at [URL]" link when the field is present.
• Updated the news issue template (.github/ISSUE_TEMPLATE/news.md) and the content template (index.mdx) to include this new field.
• Updated CONTRIBUTING.md with usage instructions.
• Added a unit test source_url.test.js to verify the rendering logic.

This fixes #7135.

Requirements

• [x] Add an optional field to the news article data model (e.g., source_url).
• [x] Update the news collection/template to read the new field.
• [x] When the field is present, display a visible link on the article page with the text: "Originally published at [Source Name or URL]".
• [x] The link should open in a new tab.
• [x] The feature must be optional and not affect articles that do not provide a source URL.
• [x] Include a short unit or visual test to verify the link is rendered only when the field exists.

Suggested tasks

• [x] Update news schema/frontmatter to include optional source_url.
• [x] Modify the news article template to conditionally render the attribution link (graphql).
• [x] Add or update one news item as an example to demonstrate the behavior.
• [x] Update the news_template.md to include an example and comment explaining the property.
• [x] Add a short note in CONTRIBUTING.md or the newsroom author guide about the new field and how to use it.

Acceptance criteria

• [x] news.md issue template has been updated.
• [x] Existing news pages with no source field remain unchanged.
• [x] A news page with original_url shows a single, clearly labeled "Originally published at" link that opens in a new tab.
• [x] The code change is documented in CONTRIBUTING or the content guide (where news authoring is described).

Notes for Reviewers You can verify this by checking any news article that has the source_url field added to its frontmatter (none are added in this PR to keep it valid for existing content, but the template is updated for future use).

Signed commits

• [x] Yes, I signed my commits.

@leecalcote , please review and give some feedback.

[leecalcote]

This is looking real good otherwise, @rishiraj38 👍

[rishiraj38]

@leecalcote Yes, source_url is fully optional. If it's not present , the UI simply doesn't render the "Originally published at" link, and the build remains unaffected.

@Rajesh-Nagarajan-11 I don’t know what’s happening. The DCO is failing yet I’m making signed commits.

@leecalcote , I’ve added the source URL to the news article that contained an eurl. Now, what do I do with the news articles that don’t have eurl?
