test/windows: load ghostty-internal.dll in CRT init reproducer

Browse Source 
The internal glue DLL was renamed from ghostty.dll to
ghostty-internal.dll. Update the LoadLibraryA call and the comment
block so this regression test still exercises the right artifact.

* Minimal reproducer for the libghostty DLL CRT initialization issue.
* Minimal reproducer for the ghostty-internal DLL CRT initialization issue.
*
* Before the fix (DllMain calling __vcrt_initialize / __acrt_initialize),
* loading ghostty.dll and calling any function that touches the C runtime
* crashed with "access violation writing 0x0000000000000024" because Zig's
* _DllMainCRTStartup does not initialize the MSVC C runtime for DLL targets.
* loading ghostty-internal.dll and calling any function that touches the C
* runtime crashed with "access violation writing 0x0000000000000024" because
* Zig's _DllMainCRTStartup does not initialize the MSVC C runtime for DLL
* targets.
*
* This test loads the DLL and calls ghostty_info, which exercises the CRT
* (string handling, memory). If it returns a version string without
* crashing, the CRT is properly initialized.
*
* Build: zig cc test_dll_init.c -o test_dll_init.exe -target native-native-msvc
* Run: copy ..\..\zig-out\lib\ghostty.dll . && test_dll_init.exe
* Run: copy ..\..\zig-out\lib\ghostty-internal.dll . && test_dll_init.exe
*
* Expected output (after fix):
* ghostty_info: <version string>
