[css-text] Bad box terminology for text-wrap

[Loirooriol]

From https://drafts.csswg.org/css-text-4/#text-wrap,

Applies to: all elements

Should probably be "Applies to: inline boxes and block containers"

Same as wrap for inline-level elements.

Should probably be "Same as wrap for inline boxes." in both occurrences

Same as wrap for block-level elements

Should probably be "Same as wrap for block containers"

For block-level elements that contain line boxes as direct children

Should probably be "For block containers that contain line boxes as direct children". But I think line 'boxes' only exist in the fragment tree so they are not really children of a box. So "For block containers that establish an inline formatting context".

Additionally, it seems wrap and nowrap don't really apply to block containers, their effect is only via inheritance to inline boxes. Consider clarifying this.

Cleaned up the wording, thanks! https://drafts.csswg.org/css-text-4/#text-wrap
