feat(replay): Add new body size field to Network table

We moved the size field in the sdk in getsentry/sentry-javascript#7589

Note that this field is for XHR/fetch and reflects the decoded body size whereas the other `data.size` fields are *transfer* size (i.e. over the network). We may want to consider changing to show decoded body size for all, though that was only recently added to the SDK.
