view 2:
The icon file of vue2 is in the public folder and is a file with the .ico suffix. We only need to put the new icon in this folder, change it to the same name, and then delete the old one to replace it.
view 3:
The vue3 icon is also in the public folder, but it is an icon with a .svg suffix. You can copy the code of the svg image from the Alibaba vector icon library and replace the code in the original vite.svg file.
