The `chplVersion` tag renders weirdly on chpl-src articles

On `*.chpl` drivern blog posts, the `chplVersion` tag does not render on each individual code block. For example

<img width="832" height="380" alt="Image" src="https://github.com/user-attachments/assets/a6a80b6d-333e-4aec-b390-96846c5d393c" />

The "Chapel X.X" tag only gets rendered on literal code blocks, not the rest of the source
