add version to extra data + moving existing versioned detectors into subdirectory format

[0x1]

Description:

• we have two ways that we set up new versions of detectors. one is to create a new directory, naming it as <detector>_v2, other is to create subdirectories <detector>/v1/ . the latter follows go convention, here we update all packages that are currently not following convention
• the adding detectors docs are also being updated to reflect this
• adding version numbers to extra data which will help distinguish which detector is causing a specific detection

Checklist:

• [ ] Tests passing (make test-community)?
• [ ] Lint passing (make lint this requires golangci-lint)?
