version.h for version 12.4 is incorrect

I updated from version 12.3 to version 12.4.
When we build, version.h is automatically generated.
However, the contents of version.h are version 12.3.

```
$ make
Create version.h
LN: platform/board to /home/nop/nuttxspace/apps/platform/dummy
Register: hello
Register: nsh
Register: sh

$ cat $HOME/nuttxspace/nuttx/include/nuttx/version.h
/* version.h -- Autogenerated! Do not edit. */

#ifndef __INCLUDE_NUTTX_VERSION_H
#define __INCLUDE_NUTTX_VERSION_H

#define CONFIG_VERSION_STRING "12.3.0" ---> incorrect
#define CONFIG_VERSION_MAJOR 12
#define CONFIG_VERSION_MINOR 3 ----> incorrect
#define CONFIG_VERSION_PATCH 0
#define CONFIG_VERSION_BUILD "9852428953"

#define CONFIG_VERSION ((CONFIG_VERSION_MAJOR << 16) |\
(CONFIG_VERSION_MINOR << 8) |\
(CONFIG_VERSION_PATCH))
```

Start by running make and inspecting nuttx/include/nuttx/version.h, then trace the version-generation step that reports "Create version.h". Reproduce the issue after updating to version 12.4 and verify that the generated header reports version 12.4 rather than 12.3.
