Update schema for version value

[M ɑ k s]

According to the documentation, you can specify the following options:

• 1.0.0-dev
• 1.0.0-alpha3
• 1.0.0-beta2
• 1.0.0-RC5
• v2.0.4-p1

However, the json schema does not follow this format.

"pattern": "^v?\\d+(\\.\\d+){0,3}|^dev-"

Need to change the schema and add support for the following suffixes: -dev, -patch (-p), -alpha (-a), -beta (-b), -RC

The schema regex only enforces the beginning looks correct, it has no $ marking the end of string so all your versions are valid. I don't really want to duplicate complex regex here and risk having it wrong or outdated, thats why the schema takes a lax approach to just validate basics are correct.
