[chore] reduce binary size (#4519)

- sets the nomsgpack build tag to instruct gin to build without msgpack support (which we don't use, anyway)
- sets the stdlibjson build tag to instruct minio to use the stdlib JSON encoder / decoder instead of goccy/json

both of the above net a size decrease of ~7MB

 # Available Go build tags, with explanation, followed by benefits of enabling it:
 # - timetzdata:     embed timezone database inside binary                          (allow setting local time inside Docker containers, at cost of 450KB)
+# - nomsgpack:      removes msgpack encoding from gin (which we don't use anyway)  (reduced binary size)
+# - stdlibjson:     sets encoding/json instead of goccy/go-json for minio          (reduced binary size)
 # - nootel:         disables compiling-in otel support                             (reduced binary size)
 # - noerrcaller:    disables caller function prefix in errors                      (slightly better performance, at cost of err readability)
 # - debug:          enables /debug/pprof endpoint                                  (adds debug, at performance cost)
