Unwanted int to float conversion

[xsilas]

Describe the bug
Using the Marshal function on a interface{} converts an integer to a float value despite the gopkg yamlv3 (gopkg.in/yaml.v3) does not:
Port somehow turns into a float:

• docker:
  file: Dockerfile
  platform:
  • arch: amd64
    os: linux
  • arch: arm64
    os: linux
    ingresses:
  • host: www
    name: website
    ports:
  • 8080.0
    resources: {}
    user: "101"

To Reproduce

yamlv3Bytes, err := yamlv3.Marshal(someInterface)
if err != nil {
return err
}
fmt.Println(string(yamlv3Bytes))

yamlBytes, err := yaml.Marshal(someInterface)
if err != nil {
return err
}
fmt.Println(string(yamlBytes))

Expected behavior
Port should remain an int like so:

• docker:
  file: Dockerfile
  platform:
  - arch: amd64
  os: linux
  - arch: arm64
  os: linux
  ingresses:
  • host: www
    name: website
    ports:
  • 8080
    resources: {}
    user: "101"
