cmake: fix git dependency for version.h creation
Fixes: #63610
Fix a variable spelling mistake which caused a required dependency to
not be set.
Together with this fix, then remove an unneeded CMake cache update.
The `ZEPHYR_GIT_INDEX-NOTFOUND` value is not really useful in this
case as a not set var will also ensure that Zephyr is checked to be
a git repo or not.
And when detected as a git repo, then `ZEPHYR_GIT_INDEX` is set
to correct value.
