fix(types): Map the UTC ZCL data type to number

zclDataTypeToValueType had no case for UTC, so generate-types threw
"Unknown ZCL type UTC" as soon as a cluster used it. The type generation
workflow has been failing on master since the Time cluster attributes
landed, leaving index.d.ts without them.
