Field names containing hyphens are truncated when serialized

[ocisly]

Describe the bug

Hyphens are legal in Kotlin field names. #383 broke serialisation of such fields by incorrectly inferring that any such field name indicates an inline class and proceeding to truncate it before the hyphen.

To Reproduce

import com.fasterxml.jackson.module.kotlin.jacksonObjectMapper

data class ReproduceBug383(val `a-b`: Int)
val mapper = jacksonObjectMapper()
mapper.writeValueAsString(ReproduceBug383(5)) // => {"a":5}

Expected behavior

{"a-b":5}

Versions
Kotlin: 1.4.31
Jackson-module-kotlin: 2.12.2
Jackson-databind: 2.12.2
