Subject: [PATCH] Remove use of struct.to_json() (#936)

Bazel 8 does not appear to support struct.to_json() anymore, so remove
its usage in vfs_overlay. It appears this API has been around since at
least 6.5 (https://bazel.build/versions/6.5.0/rules/lib/core/json), so
changing to it shouldn't be an issue.
