Icon: Mistake in example documentation code

[shaman-apprentice]

Describe the bug

The following example code in https://primeng.org/icons#color is not working as expected: <i class="pi pi-search" style="color: 'var(--primary-color)'"></i>

I guess the quotes around the css var are a copy paste mistake. I will quickly create a PR to fix / update the documentation.
