Update data layers in NDVI narrative

[j08lue]

Our new V1 products perform much better than the V0 ones and should be used in the NDVI narrative instead of the currently referenced one, some of which are also not available in the sentinel-2-l2a collection anymore.

Currently used scenes

• /collections/sentinel-2-l2a/items/S2C_MSIL2A_20250913T095041_N0511_R079_T33TVF_20250913T151113
• /collections/sentinel-2-l2a/items/S2B_MSIL2A_20250804T103629_N0511_R008_T31TDH_20250804T130722
• /collections/sentinel-2-l2a/items/S2A_MSIL2A_20250831T103701_N0511_R008_T31TDH_20250831T145420

Is this issue still valid, @emmanuelmathot / was it ever?

We did not change the product IDs in the story, but it seems to load fine now? https://explorer.eopf.copernicus.eu/story/?id=ndvi

Let's keep it open as the "How did we build this?" section needs to be updated to link to the documentation
