Hugo Config option for blog URLs: avoid deprecation (#2439)

* Hugo Config option for blog URLs: avoid deprecation

    WARN  deprecated: the ":filename" permalink token was deprecated in Hugo 0.144.0 and will be removed in a future release. Use ":contentbasename" instead.

* Refer to latest Hugo release

* Hugo: stop using getJSON

I looked at https://discourse.gohugo.io/t/how-to-replace-the-data-getjson-with-resources-getremote-or-resources-get/52728/4 to learn a little about how to do it.
