title not rendered in Enumeratum-derived String Enums

Describe the bug

If I create an Enumeratum Enum, and use either the @title annotation or withTitle directly on the schema, the title is not shown in the rendered JSON Schema.

To Reproduce

Welcome to Scala 2.12.15 (OpenJDK 64-Bit Server VM, Java 11.0.15).
Type in expressions for evaluation. Or try :help.

scala> import enumeratum.Enum
import enumeratum.Enum

scala> import enumeratum.EnumEntry
import enumeratum.EnumEntry

scala> import json.schema._
import json.schema._

scala> :paste
// Entering paste mode (ctrl-D to finish)

@title("foo")
sealed trait Foo extends EnumEntry
object Foo extends Enum[Foo] {
  val values = findValues

  case object Bar extends Foo
  case object Baz extends Foo

  import com.github.andyglow.jsonschema.EnumeratumSupport._
  implicit val jsonSchema = json.Json.schema[Foo]
}

// Exiting paste mode, now interpreting.

defined trait Foo
defined object Foo

scala> println(Foo.jsonSchema)
enum[string]("Bar","Baz") title=`foo`

scala> import com.github.andyglow.jsonschema.AsCirce._
import com.github.andyglow.jsonschema.AsCirce._

scala> import json.schema.Version._
import json.schema.Version._

scala> Foo.jsonSchema.asCirce(Draft04()).spaces2
res1: String =
{
  "$schema" : "http://json-schema.org/draft-04/schema#",
  "type" : "string",
  "enum" : [
    "Bar",
    "Baz"
  ]
}

Expected behavior I expect the output to be

{
  "$schema" : "http://json-schema.org/draft-04/schema#",
  "type" : "string",
  "title": "foo",
  "enum" : [
    "Bar",
    "Baz"
  ]
}

Actual results See above.

Versions:

0.7.8
2.12.15

Additional context I tried additional Draft versions, all behave the same. I had a look at json-schema.org and didn't see anything that suggested the title shouldn't be there. Using an app like http://json-schema.app, the title attribute is used if I manually add it.
