Validation of module version

[loispostula]

The terraform registry protocol state that module version should follow strict semver specification.

A validation should be added to the module endpoint

Thanks for this input, while i see your point, i think users of Tapir should be free to choose on a versioning strategy. Although it is recommended to go with SemVer i dont see a drawback in not enforcing it :)

After this popped up in #455 again, i saw that i was mistaken. Hence this will be added soon. Thanks again for reporting this
