Update default texture anisotropy value from 0 to 1

[thibka]

Fix a small typo in the documentation. The default value for anisotropy is 1, not 0.

The docs are now auto generated. You should fix this instead:

three.js/src/textures/Texture.js

Lines 154 to 163 in bd2462f

	/**
	* The number of samples taken along the axis through the pixel that has the
	* highest density of texels. By default, this value is `1`. A higher value
	* gives a less blurry result than a basic mipmap, at the cost of more
	* texture samples being used.
	*
	* @type {number}
	* @default 0
	*/
	this.anisotropy = anisotropy;

But... To be more correct, it should say the the default value is Texture.DEFAULT_ANISOTROPY 🤔

Indeed. Let's use Texture.DEFAULT_ANISOTROPY. The ctor parameter is already documented that way.

I believe when I initially wrote this JSDoc, I wasn't sure if using Texture.DEFAULT_ANISOTROPY with the @default tag produces a parsing error. But I've tested it now and turns out it works just fine.
