`DEFAULT_REMOTE_ICON` uses wrong code

[bedlamzd]

Describe the bug
Default remote icon is displayed incorrectly due to wrong code format. The character used is \uf02a  with literal 2 added at the end.

If I understand correctly, this is because actual character code (\uf02a2) is longer then 4 hex digits, which makes it render as 2. For proper display \U000f02a2 code should be used.

To Reproduce
Have nerd fonts enabled?

mkdir lzg-test && cd lzg-test
git init
git remote add test https://example.com

Open lazygit and navigate to remotes pane, see the wrong icon 2

Expected behavior
According to this line the icon should be \U000f02a2 󰊢
