FR: Add option to add Word Count to metadata

[thiagowfx]

In addition to showReadingTime ("5 min"), it would be handy to have native support for showWordCount or similar ("100 words").

Rationale: Reading time is subjective and relative. Word count is absolute and a more reliable and traditional proxy to estimate how long a post is. It's not perfect, and there are variations across languages, hence an option would leave it to users to decide whether it's relevant to their use cases.

Proof-of-concept

• Commit: thiagowfx/thiagowfx.github.io@cf02321
• Live example: https://thiagowfx.github.io/2021/12/hello-world-from-hugo/

It basically comes down to adding the following snippet to post_meta.html:

{{- if (.Param "ShowWordCount") -}}
{{- $scratch.Add "meta" (slice (i18n "words" .WordCount | default (printf "%d words" .WordCount))) }}
{{- end }}

...plus adding translations for "words".

And the metadata looks something like:

December 11, 2021 · 1 min · 28 words · Thiago Perrotta

Happy to send a more polished PR than the aforementioned commit if the developers are willing to accept this contribution.
