DevTools error boundary: Search for pre-existing GH issues

Previously the error boundary UI in DevTools showed a link to report the error on GitHub. This was helpful but resulted in a lot of duplicate issues. This commit adds an intermediate step of searching GitHub issues (using the public API) to find a pre-existing match and linking to it instead if one is found. Hopefully this will encourage people to add info to existing issues rather than report duplicates.
