Depending on the number of translated languages, the word "all" will be translated differently in many languages. These rows need to be constructed with _n()

printf(
	/* translators: %s: Number of available languages */
	_x( 'See all %s', 'languages' ),
	$available_languages_count
)

That string is also missing a text domain.

There's also _x( 'See all %s', 'plugins', 'wporg-plugins' ) string in the theme.
