Fix version validation for nightlies

Summary:
The nightly version is bumped after the check is performed, therefore it fails.

With this diff, we become slightly more accepting with nightlies, allowing both `0.0.0` and `0.0.0-xxxx` as valid version for nightlies.

## Changelog
[JS][Fixed] - Accept 0.0.0 with and without prelrelease for nightlies' versions
