Allow adding a dynamic @since tag that adjusts automatically

[RaananW]

Fixes #13209

This script will be running during the publish CI process and update all tags marked with @SInCE with nothing after (newline only) something like this:

/**
 * This function does nothing, please use it as much as you want
 * @since
 */
buyNFT();

If there is anything after the @SInCE tag it will not be processed.
