Add icons for fonts, astro, content, and admin

[nqnduy]

Hi Littensy
First of all, thank you for creating this amazing extension! I find it extremely helpful in my daily work.
I would like to request additional icons for certain file types commonly used in my projects. Specifically, I need icons for:

• Astro files (.astro)
• Font files: .tft, .woff, .woff2, .eot, ..

These icons would help distinguish these files visually in the editor, making navigation more efficient. I believe other users would also benefit from having these icons available.

Thank you very much for considering my request! Looking forward to any updates on this feature.
Best regards,
Duy
