go.mod: bump github.com/go-json-experiment/json (#15010)

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
