fix: modify the config default value keep consistency

[jujiale]

this is a config style optimize, nothing to do with core logic.
In config.go
there are some configs have default value, such as the following port 8082 and 8379
`

      type http struct {
      Enabled bool `config:"enabled" default:"true"`
      Port    int  `config:"port" default:"8082" validate:"number,gte=0,lte=65535"`
  }
  
  type websocket struct {
      Enabled                 bool          `config:"enabled" default:"true"`
      Port                    int           `config:"port" default:"8379" validate:"number,gte=0,lte=65535"`
      MaxWriteResponseRetries int           `config:"max_write_response_retries" default:"3" validate:"min=0"`
      WriteResponseTimeout    time.Duration `config:"write_response_timeout" default:"10s"`
  }

`

but in cli.go the default value is not the same, such as the following port 7380 and 7381
`

    flag.IntVar(&flagsConfig.HTTP.Port, "http-port", 7380, "port for accepting requets over HTTP")
    flag.BoolVar(&flagsConfig.HTTP.Enabled, "enable-http", false, "enable DiceDB to listen, accept, and process HTTP")

    flag.IntVar(&flagsConfig.WebSocket.Port, "websocket-port", 7381, "port for accepting requets over WebSocket")

`

this pr only keep them the same so that default config value keep consistency.

I think the test case failed has nothing to do with this pr, please have a check, thanks.
