Fix modinfo.lua version variable for smoke tests

- Replace $VERSION placeholder with "test" for CI smoke tests
- This fixes "SpringBoard Core" not being found error
- Spring concatenates name + " " + version, so "SpringBoard Core" + "test"
  = "SpringBoard Core test"
- Script.txt now correctly references "SpringBoard Core test"

Issue: Map texture loading still causes segfault at "Loading Square Textures"
- Need to create proper DXT1-compressed SMT texture files
- Or find alternative minimal map with working textures
