Chinese translation error in the BBCode tag reference table.

[BrotherShort]

Your Godot version: v4.8dev

Issue description:
There is a Chinese translation error in the img cell in the BBCode tag reference table.
English:

Add % to the end of {width} or {height} value to specify it as percentages of the control width instead of pixels.

Current Chinese translation:

在 {宽度} 和 {高度} 取值的末尾加上 % 可以指定控件宽高的百分比，而不是像素。

Expected Chinese translation:

在 {宽度} 和 {高度} 取值的末尾加上 % 可以指定控件宽度的百分比，而不是像素。

"宽高" is wrong. "宽度" is right.
