Transifex pluralization configuration

[yolile]

There are some strings in transifex that can only be in the plural, like this one:

but they are configured as pluralizable so the translator must fill in the singular and plural translation.

I see the code for these:

spoonbill-web/frontend/src/components/CustomizeTables/CustomizeTablesTable.vue

Lines 246 to 274 in f595929

	case 1:
	translated = this.$ngettext('There is one array in this table', 'There is one array in this table');
	break;
	case 2:
	translated = this.$ngettext('There are two arrays in this table', 'There are two arrays in this table');
	break;
	case 3:
	translated = this.$ngettext(
	'There are three arrays in this table',
	'There are three arrays in this table'
	);
	break;
	case 4:
	translated = this.$ngettext(
	'There are four arrays in this table',
	'There are four arrays in this table"'
	);
	break;
	case 5:
	translated = this.$ngettext(
	'There are five arrays in this table',
	'There are five arrays in this table'
	);
	break;
	default:
	translated = this.$ngettext(
	'There is %{ n } array in this table',
	'There are %{ n } arrays in this table'
	);

I think it's fine to remove the cases 1-5 and just use numbers like in the default case instead of "one", "two", "three", etc.

@sabahfromlondon I don't know if you had a strong opinion on words vs. numbers? Words unfortunately make for very repetitive code.
