fix: Link for connect button

[andreaskienle]

This PR fixes the link used by the Connect button when multiple contexts are present.

We previously removed the context from the URL (see #206), but this instance was missed.

Pull Request Overview

This PR fixes the URL construction for the Connect button by removing the context parameter from the path. This aligns with a previous change that removed context from URLs throughout the application but was missed in this specific component.

• Removes /context/${context.name} from the data-target URL path
• Ensures consistency with the URL structure established in PR #206
