Internationalize and localize the sb/children-block

[bobbingwide]

Do for sb/children-block what I did for sb/breadcrumbs-block - internationalize it and create localized versions for UK English ( en_GB ) and bbboing ( bb_BB ).

Proposed solution

• [x] Update package.json to add makepot and makejson
• [x] Add logic to set script translations for translation of JavaScript strings
• [x] Add logic to load plugin textdomain for translation of PHP strings
• [x] Internationalize strings in the source files
• [x] Localize
• [x] Test in bb_BB language
• [x] While we're at it check that none of the sb/parent-block stuff remains

$ok = wp_set_script_translations( 'sb-children-block-block-editor', 'sb-children-block' , $dir .'/languages'  );
load_plugin_textdomain( 'sb-children-block', false, 'sb-children-block/languages' );

Test in bb_BB language

There are only 4 strings we can really see.

But if we use oik-blockinfo we can see the keywords as well, and we can search on the keywords too.

Question: Should the category 'widgets' be translated or not?

Closing this even though:

• there are no automated tests of the PHP or JavaScript code
• there's CSS that applies to classes that don't get generated
• I'm no longer sure if the "block" part of the name ( "Children block" ) is actually required.
