Fix version.txt validation logic for export templates .tpz

It assumed that the version would always be `x.y-status`,
with no dot possible in `status`, so:
- It would not work for 3.0.1-stable (nor 3.0.1.stable with new version logic)
- It would not support Mono templates when we provide them

The validation it did was not really useful anyway, so we just use the raw
string.
