Pull Request resolves #48033.

Summary of Changes

The Schema.org JobPosting plugin emits the stored form values Telecommute, Onsite or Hybrid directly as jobLocationType in the JSON-LD output. Google for Jobs only accepts TELECOMMUTE for this property, so the generated markup is flagged as invalid by the Rich Results Test. This PR maps the stored values at output time in onSchemaBeforeCompileHead: Telecommute and Hybrid become TELECOMMUTE (a hybrid job keeps its physical jobLocation alongside, which Google interprets as hybrid), and Onsite omits jobLocationType entirely and relies on jobLocation. The form and stored data are unchanged, so existing sites need no migration.

A unit test for the plugin is included. It fails against the current code (Hybrid and Onsite pass through unchanged) and passes with this change; the rest of the Unit suite is unaffected.

Disclosure per the Generative AI policy: this contribution was created with the help of an AI assistant (Claude). The bug was reproduced, the fix was written and the tests were run and verified by the tool under human direction, and the result was reviewed before submission.

Testing Instructions

1. Enable the "System - Schema.org" and "Schema.org - JobPosting" plugins, and set Schema.org as active for articles.
2. Create an article, open its Schema tab, select the JobPosting type, and set the job location field to Onsite (repeat later with Hybrid and Telecommute). Save.
3. View the article on the frontend and inspect the application/ld+json block in the page source, or run the URL through Google's Rich Results Test.

Actual result BEFORE applying this Pull Request

The JSON-LD contains "jobLocationType": "Onsite" (or "Hybrid" / "Telecommute"), which Google flags as invalid.

Expected result AFTER applying this Pull Request

Onsite: no jobLocationType in the output, only jobLocation. Hybrid and Telecommute: "jobLocationType": "TELECOMMUTE", with the physical jobLocation still present for Hybrid.
