Decorator can't act on Tags that are not at root.

Describe the bug
Our swagger spec has tags as part of the operation, I am trying to write a custom decorator to reformat these, however my code will not trigger on the TagList item if the tags are not at the root level.

To Reproduce
Steps to reproduce the behavior:
This is a sample of the OAS spec

{
  "openapi": "3.0.1",
  "info": {
    "title": "Test",
    "version": "1.0"
  },
  "tags": [
    "TestTag"
  ],
  "paths": {
    "/api/v1/apitokens": {
      "get": {
        "summary": "List the API Tokens used to access this API",
        "tags": [
          "ApiTokensControllerV1"
        ],
        "responses": {
          "200": {
            "description": "Success",
            "content": {
              "application/json": {
                "schema": {
                  "$ref": "#/components/schemas/ApiTokenReadModelV1ListMethodResult"
                }
              },
            }
          }
        }
      }
    }
  }
}

And this is my custom plugin

module.exports = RewriteTags;

/** @type {import('@redocly/cli').OasDecorator} */
function RewriteTags({tag}) {
  return {
    TagList: {
      leave(t) {
        console.log(t)
      }
    }
  }
};

When this is run it logs out the TestTag at the root but not the ApiTokensControllerV1 tag in the get operation

Expected behavior
Should act on tags at all levels

Logs

OpenAPI definition

Redocly Version(s)

Node.js Version(s)

Start with the OasDecorator and TagList traversal used by the custom RewriteTags plugin, then reproduce the example with both root-level and operation-level tags. Done means the decorator observes and can process TagList items at both levels, with a test covering the nested operation tag.
