fix(frontend): fix public github repo cannot be selected

[xyeric]

Current behavior：

Public Github repo cannot be selected.

Cause analysis:

In file github-repo-selector.tsx，the original intention of this line L34 perhaps to deduplicate two lists, but public repo list has filtered with it self, causing the selected repo cannot be matched in the select event hander.

Proposed solution

filter public repo list with user repo list.

🍰 - Good catch. Making sure that the public repos are not in the user repo list - rather than in itself
