Update ECPS Beta-launch blog post to reflect correct dataset link

[PavelMakarchuk]

The blog post includes:

ecps = Microsimulation(dataset="enhanced_cps_2024")

But it should be:

ecps = Microsimulation(dataset="hf://policyengine/policyengine-us-data/enhanced_cps_2024.h5")

Does this still need to be done?

Thank you for filing this issue. Closing as part of the policyengine-app (v1) wind-down: policyengine.org is now served by policyengine-app-v2, and this repository is being archived, so this issue is frozen against a codebase that no longer deploys anywhere.

If this is still relevant on the current site, please re-file it against policyengine-app-v2 — we'd welcome it there. Apologies that this sat open through the migration.
