FIX: fix OGP URLs, see #471

[dfsp-spirit]

Minor fix of typo in EGL URL, as reported in #471.

Description

Related issue: #471

Motivation and context

Broken URL.

How has this been tested?

• Tested new versus old URL in webbrowser.
• ran tests locally (hatch run test tests/api), which succeeded, but it also did before this fix. Adding a new test for this trivial change seems exaggerated though.

Screenshots (if appropriate)
