Wrong URL in the README

[zhouxixi20-cell]

The marketplace URL in the README quick-start (https://github.com/anthropics/claude-for-financial-services) returns "Repository not accessible" in Cowork's Add marketplace dialog. The correct URL is https://github.com/anthropics/financial-services-plugins.
