feat(frontend): enhance GitHub repo picker with search and sorting

[rbren]

This PR enhances the GitHub repository picker with the following features:

• Add GitHub API search for public repos when user enters a query
• Show stargazer count for searched repos
• Keep repos sorted by pushed_at (most recent first)
• Place searched repo at the top of the picker

To run this PR locally, use the following command:

docker run -it --rm   -p 3000:3000   -v /var/run/docker.sock:/var/run/docker.sock   --add-host host.docker.internal:host-gateway   -e SANDBOX_RUNTIME_CONTAINER_IMAGE=docker.all-hands.dev/all-hands-ai/runtime:66286b2-nikolaik   --name openhands-app-66286b2   docker.all-hands.dev/all-hands-ai/openhands:66286b2

I tested this and the behavior of the search functionality is somewhat unintuitive. For instance, I did:

Lightning-AI/lit and it gave me a result of Lightning-AI/lit-llama (which has about 6000 stars) and then I continued typing Lightning-AI/litgpt and got Lightning-AI/litgpt (which has 10,000 stars). It seems that maybe it should display more than one result when it searces public repos, and it should sort in descending order of stars, given that stars are displayed in the interface.

OVERVIEW:
All issues appear to be successfully resolved. The changes implemented include:

• Expanded search results (5 repos instead of 1)
• Added popularity-based sorting (by stars)
• Enhanced UI with multiple results and star counts
• Preserved star count visibility for public repos

STATUS: ✅ FULLY RESOLVED
No remaining issues identified; changes successfully improve both functionality and user experience of the repository search feature.

Overview:
✓ Issue fully resolved

• Original problem: Personal repositories were shown regardless of search terms
• Solution implemented: Added proper filtering of personal repos based on search query
• Key fix: Filter condition checks if repo name matches search term
• Expected behavior maintained for empty searches

No remaining issues identified - the implementation appears to completely address the reported problem.

Tests are the things that look the most off, the rest is starting to look real good
