Added support linear gradient angles for text gradients. Added gradient unit parsing(deg, grad, rad, turn). Removed redundant tags text-background & text-background-image `color: linear-gradient( 90deg, rgba(255,0,0,1), rgba(255,154,0,1), rgba(208,222,33,1), rgba(79,220,74,1), rgba(63,218,216,1), rgba(47,201,226,1), rgba(28,127,238,1), rgba(95,21,242,1), rgba(186,12,248,1), rgba(251,7,217,1), rgba(255,0,0,1) );` https://files.facepunch.com/ognik/1b1611b1/2022-01-03_55-22-5eb08044-4257-4bc3-a3b0-02b34cbce225-6MQT2b5S.png
