versions.md misuses 1.0 in a semver example

[ElectricNroff]

https://github.com/CVEProject/cve-schema/blob/2aa608b6733cc2730a43901472ef0e706d0ef2b5/schema/v5.0/docs/versions.md has an example of

{
	"version": "1.0",
	"versionType": "semver",
	"lessThan": "2.*",
	"status": "affected"
}

but this should instead be written as:

{
	"version": "1.0.0",
	"versionType": "semver",
	"lessThan": "2.*",
	"status": "affected"
}

because version 1.0 cannot exist when semantic versioning is used: https://semver.org

Fixed in above commit via develop branch. Will go into next release after 5.1.1.
