Classic Texture Fix

- Updated pack icon to match the Java pack - Renamed pack name back to "Classic Textures Fix" - The classic, literally "crying" obsidian, along with its blue light in Vibrant Visuals, is now the default option, instead of being limited to the Java Parity subpack - Added the large interaction button in touch control - Slightly changed the texture of Glass - Slightly changed the texture of Zombified Piglin - Fixed an issue where rabbits still use the old model - Updated `glyph_E1.png` - Note: I'm not going to add classic textures for other touch controls as of now, because: - The new touch controls behave inconsistently with the old one, and it's hard to make appropriate textures - Retexturing the top buttons requires to modify `gui.png`, which leads to a lot of glitches due to Bedrock Edition's texture backwards compatibility mapping
