The upstream module has seen significant work making the v1 emulation layer a high fidelity re-implementation of v1 "encoding/json". This addresses several upstream breaking changes: * MarshalJSONV2 renamed as MarshalJSONTo * UnmarshalJSONV2 renamed as UnmarshalJSONFrom * Options argument removed from MarshalJSONV2 * Options argument removed from UnmarshalJSONV2 Updates tailscale/corp#791 Signed-off-by: Joe Tsai <joetsai@digital-static.net>
