fixed nerd-font icons

[ronit1996]

Fixed the nerd font icons as the old ones didn't work on the updated nerd fonts, the icons are same just the names got changed in the website.

Is this issue present in the deathemonic version?

Also people can check this issue for more information. TL;DR of it is some of the Unicode codepoints used where not free for use, meaning they where already occupied so some of them where changed around to prevent issues to my best understanding

ryanoasis/nerd-fonts#1190

Perhaps this could cause issues with people with older nerd fonts versions though? Perhaps Debian or more stable distros decide not to ship it as soon, maybe a branch or separate version might need to be made

I didn't check the deathmonic version but what I found out is that they had changed the codes for various icons, and hence those codes starting showing different icons.

Running nerdfix check it alerted about some obsolete icons (for basic and the deathmonic versions).
I had to use nerdfix fix to properly display them.

I will submit another PR with everything fixed as OP doesn't seem active

Closing as #22 supersedes this
