Introspection opcode returns garbage when scenario sets version greater than int32

[A60AB5450353F40E]

Reproduce for scenario with:

"version": 3953915070, (0xbef4abeb)

OP_TXVERSION returns -341052226 (0x420b5494) when I'd expect it to return -1806431422 (0xbef4abeb)

Found while trying to implement BTC's CTV test vector, import the below template and look at test_0 line 9:
