Add sample @fr-tagged version of gist annotations

[rjyounes]

See #685. We decided that this could be either partial (as an example), or complete.

@JessSing @turingtest37 Any volunteers? This is not till release 13, at least 6 months away.

TBD: File naming conventions, file and directory structure

• One directory for each language or a shared directory for all languages?
• One file per language, or mirroring the canonical files with 5 separate files? If the latter, there should be a directory per language to avoid clutter.
• The release package generates multiple serializations of each file, so having one directory per sub-language seems cleaner and more manageable.

Also TBD whether to use 2- or 4-digit tags. See discussion thread on issue #685.

Adding status "under review" until these questions are answered.

Team discussion on 2023-05-25 led to the following conclusions:

  * Related issues: 
	  * [Automated generation of en version](https://github.com/semanticarts/gist/issues/840)
	  * [Sample French version](https://github.com/semanticarts/gist/issues/841)
	  * [Sample Spanish version](https://github.com/semanticarts/gist/issues/851) (Pat McBennett to submit PR)
	  * [Documentation](https://github.com/semanticarts/gist/issues/842)
* Open discussion points
    * Language or language+subtag? Subtag could be region or script. E.g., in Chinese the script is of primary significance in written text, not the region. From John Cowan.
      * Maybe language only if there are no significant regional distinctions, otherwise language+region? (Note, for accuracy the subtags are not always 2 letters). 
      * Don't need to prescribe, just let people submit what they want to? We could reject a region tag where there are no regional distinctions.
      * What do we want to do for our versions?
	      * English - use language only, may change in future
	      * French - use language only, may change in future
     * How do we review PRs in language we have no expertise in? 
         * Trust factor
         * In-house expertise
	     * Test in Google translate (to English), if they look OK accept them. If not, reject the whole batch.
	     * Add disclaimer for those we haven't been able to review, and also that they may not be up-to-date as gist evolves.
	     * SA in-house expertise:
		     * French: Doug, Jess
		     * German: Rebecca
		     * Arabic: Dalia
		     * Simplified and Traditional Chinese: Katie (some)
		     * Japanese: Katie (some)
		     * Russian: Irina
		     * Italian: Irina
    * No default untagged version - our default should be `en-US`. From John Cowan.
      * Then this is a major change.
      * Decision: keep untagged versions as defaults in ontology files. Can change later in a major release. 
    *  File names and directory structure. 
	    * Only release in Turtle. 
	    * Most likely only gistCore, not supplementary ontologies, will be translated.
	    * There might be a translation of the readme if someone wants to do it.
	    * So, we'll only have one ontology file per language. Naming conventions:
		    * `gistCore.en.ttl`
		    * `README.en.md`
	    * So use one directory. [We didn't decide on a directory name, I propose `language_tagged_annotations` or similar.]
