[BUG] encodedName of a root coproduct type is applied to sub-types

[jumale]

Tapir version: 1.9.5

Scala version: 2.13

Note: I'm not completely sure if in general this is a valid use-case for encodedName, because in Tapir-documentation it's only mentioned as an annotation for class-fields, but it does not say anything about classes themselves.

Describe the bug

When annotating a sealed trait with encodedName - the encoded name is applied to both the parent trait and all it's sub-types, unless they have their own encodedName.
As you can see in the example below - the trait has 3 sub-types Foo/Bar/Baz.
The root type and one of sub-types are annotated with custom encoded name.
The resulting derived schema has correct encoded names for MyType and Foo, however Bar and Baz are both named as their parent "CustomMyType", which probably also resulted in replacing Bar with Baz in the list of subtypes.

How to reproduce?

import sttp.tapir.Schema
import sttp.tapir.Schema.annotations.encodedName

// given
@encodedName("CustomMyType")
sealed trait MyType

object MyType {

  @encodedName("CustomFoo")
  final case class Foo(a: String)  extends MyType
  final case class Bar(b: Int)     extends MyType
  final case class Baz(c: Boolean) extends MyType
}

// when
val schema = Schema.derived[MyType]

// then schema results in
Schema(
  name = Some(SName("CustomMyType")),
  discriminator = None,
  schemaType = SCoproduct(
    subtypes = List(
      Schema(
        schemaType = SProduct(List(SProductField(FieldName(a,a),Schema(SString(), ...)))),
        name = Some(SName("CustomFoo")),
        ...
      ),
      Schema(
        schemaType = SProduct(List(SProductField(FieldName(c,c),Schema(SBoolean(), ...)))),
        name = Some(SName("CustomMyType")),
        ...
      )
    )
  ),
  ...
)
