Clarify the 1.0.107 release notes #5377

The 1.0.106 and 1.0.107 release notes differ only in their dates. The corresponding sections in changelog.md differ only in their headings.

The npm metadata for both @github/copilot versions has the same buildMetadata.gitCommit.

Does 1.0.107 include functional changes relative to 1.0.106? Could you update the 1.0.107 release notes and changelog section with the answer?
