plotly-locale-nl-latest.js shortDays

In Dutch it is common to abbreviate weekdays using two characters instead of three (cf: Onze Taal).

Using the abbreviation vri for vrijdag (friday) is very strange as ij (y) is considered on character in Dutch, it should either be vr or vrij.

I suggest to update the translation as follows:
shortDays: ['zo', 'ma', 'di', 'wo', 'do', 'vr', 'za'],

打开 plotly-locale-nl-latest.js 并定位荷兰语的 shortDays 翻译。将现有的星期缩写与 issue 提议的两个字符值进行比较，然后验证 locale 包含所请求的数组，并且没有更改无关的翻译。
