[BUG] Problem with type names in Avro unions

[YuriiKondratov]

Description

When I generate HTML from asyncapi specification referencing Avro schema with unions, I get unexpected "Adheres to undefined.... Or to undefined...." construct.

To reproduce bug create file "OuterRecord.avsc" with schema:

{
  "type" : "record",
  "name" : "OuterRecord",
  "doc" : "OuterRecord docstring",
  "fields" : [ {
    "name" : "innerRecord",
    "type" : [ {
      "type" : "record",
      "name" : "InnerRecord1",
      "doc" : "InnerRecord1 docstring",
      "fields" : [ {
        "name" : "innerRecord1Field",
        "type" : "string",
        "doc" : "innerRecord1Field docstring"
      } ]
    }, {
      "type" : "record",
      "name" : "InnerRecord2",
      "doc" : "InnerRecord2 docstring",
      "fields" : [ {
        "name" : "innerRecord2Field",
        "type" : "string",
        "doc" : "innerRecord2Field docstring"
      } ]
    } ],
    "doc" : "innerRecord docstring"
  } ]
}

and file "asyncapi.yaml" with specification:

asyncapi: 3.0.0

      payload:
        schemaFormat: 'application/vnd.apache.avro;version=1.9.0'
        schema:
          $ref: './OuterRecord.avsc'

then generate HTML using

npm install -g @asyncapi/cli
asyncapi generate fromTemplate asyncapi.yaml @asyncapi/html-template@2.3.9

Expected result

In section Messages.Payload.innerRecord I expect to see "Adheres to InnerRecord1 .... Or to InnerRecord2 ...."

Actual result

I get "Adheres to undefined.... Or to undefined...."
