fix(index): the funding card named the wrong NSF programme

The card said "NSF POSE Phase I" and linked NSF 24-606, Pathways to Enable
Open-Source Ecosystems. The submission is to PESOSE, Pathways to Enable
Secure Open-Source Ecosystems, NSF 26-506, which is a different and current
solicitation. PESOSE awards Tracks rather than Phases, matching the proposal
we filed as Track 1.

Three errors in one card, on the page that tells readers what AgenTrust has
applied for. Caught by Kavya Pearlman, who is leading the submission.
