 * The new --experimental-strip-types node option conflicts with `ts-node`.
 * This wrapper disables it if it's supported by the current node version.

 * See: https://github.com/TypeStrong/ts-node/issues/2152
 *
 * TODO: switch to native typescript support once node<22 are dropped.
