Endpoints with double-asterisk in the path are excluded from the Swagger output

[mc1arke]

Describe the bug

Since 2.7.0, a path that contains a double asterisk do not get included in the Swagger output.

To Reproduce
Steps to reproduce the behaviour:

1. Define an endpoint with a double asterisk in the path matching

@RestController
public class WildcardController {
    @PostMapping("/**")
    @Operation(summary = "My Wildcard Operation")
    public String getItem(HttpServletRequest request) {
        return request.getPathInfo();
    }
}

2. Check the swagger output

Expected behaviour

The endpoint to be included in the swagger output, e.g.

{
  "openapi": "3.1.0",
  "info": {
    "title": "OpenAPI definition",
    "version": "v0"
  },
  "servers": [
    {
      "url": "http://localhost",
      "description": "Generated server url"
    }
  ],
  "paths": {
    "/**": {
      "post": {
        "tags": [
          "wildcard-controller"
        ],
        "summary": "My Wildcard Operation",
        "operationId": "getItem",
        "responses": {
          "200": {
            "description": "OK",
            "content": {
              "*/*": {
                "schema": {
                  "type": "string"
                }
              }
            }
          }
        }
      }
    }
  },
  "components": {}
}

Additional context
1a9a1d4 appears to be the cause of this, which presumably was only supposed to filter out actuator endpoints that contained double asterisks, but is also filtering out non-actuator endpoints
