feat(frontend): push to cloud if needed for marketplace, and add a download agent button

[ntindle]

Background

""" We require a quick emergency fix for our self-host users so that they are able to use the marketplace.

This is that fix.

1. In this PR we make the "Marketplace" link in the navbar open a popup window which opens: http://platform.agpt.co/marketplace

2. On this website, self-host users are able to browse and download agents to a file without logging in, as this PR adds a "download to file" button.

After this, we will explore the next steps towards a more long-term solution. ~ Toran """

⚡ Key issues to review Conditional Routing The Marketplace link now conditionally routes to different URLs based on the getBehaveAs() function. This change might affect navigation and user experience. New Functionality A new downloadAgent function has been added to allow users to download agent files. This introduces new functionality that should be thoroughly tested. UI Changes The UI has been updated to include a new "Download Agent" button alongside the existing "Save to Templates" button. This change affects the user interface and should be reviewed for consistency and usability.
