Implement missing swiftfindrefs --version

[Nikoloutsos]

By merging this PR we will be able to use swiftfindrefs --version.

> swiftfindrefs --version
1.0.1

current behavior is the following

> swiftfindrefs --version
Error: Provide either --projectName or --derivedDataPath.
Usage: swift-find-refs search [--projectName <projectName>] [--derivedDataPath <derivedDataPath>] [--verbose] --symbolName <symbolName> [--symbolType <symbolType>]
  See 'swift-find-refs search --help' for more information.

This is a simple but important addition that will help with debugging especially when users report issues, knowing the exact version.

thanks @Nikoloutsos ❤️ !

Can we read the version using this https://github.com/michaelversus/SwiftFindRefs/blob/master/VERSION?
We have a workflow for the releases and it will be very convenient having this as single source of truth.

[Nikoloutsos]

Good point, sure I can try it out. Better for the version to be in 1 place.

Following up, VERSION has been moved inside Sources to be able to be copied from bundle (5a96132)
Also all scripts pointing to old path have been renewed.
