feat: add more rules to [filetype] and [icon]

[Brixy]

This adds rules for empty files, links and executables.

Coloring is based on eza's default theme. This also seems to be a default across terminal file managers.

Closes #963

OK. Changed.

• Cyan is used for links which is common.
• Red is just used once for empty files.
• Images and audios/videos use the same color, but audio and video filetypes are boldened. (This is approximately what eza does, yet with purple instead of yazi’s yellow.)

I also tested underlining links, but it was confusing as underlining is used in the preview windows.

Thanks, I made some adjustments:

• Removed the bold/crossed attribute and used different colors for distinction, as I found it wasn't very clear and overlapped with other bold text, such as emphasizing search keywords
• Removed empty files but kept it there as an example, and I will also add them to the document
• Used a background color for orphan instead of a foreground color, because the red foreground color is used for archived files
• Removed link since there weren't enough colors, but I think having the filename to the right of the link to the linked file with "->" is distinctive enough, and I added a separate icon for it in the icon rules
• Added icons for special files.

Excellent! Thank you.
