Fix bun server integration from latest bun changes #15941
Description
Description
In the Bun SDK we pin bun-types to latest in our dev deps.
The issue with this is that it gets stale with the latest version of bun.
In Bun 1.2.6 the changes have broken the types for Bun.serve, which breaks our instrumentation. This was not accounted for because our bun-types were pinned to an older version so we didn't see.
