fix(blink): make sure to use LazyVim.config.icons.kinds (#5668)

## Description
This blink
[commit](010d939e7f)
made a change, so that third party sources can provide their own
`item.kind_icon` and `item.kind_name`. The problem is that these icons
will take precedence over `config.kind_icons[kind]`, which LazyVim sets
[here](541b83276e/lua/lazyvim/plugins/extras/coding/blink.lua (L164-L164)).

I noticed that `blink-cmp-copilot` also started providing its own in the
items that it returns. I noticed this because I have the following in my
configuration `columns = { { "label", "label_description", gap = 1 }, {
"kind_icon", "kind" } }`. The icon that it uses is a smaller icon one
character long, which by default it will scale up and show normally like
the LazyVim icon. But when you put another component next to it (like
`kind`) in the `columns` field, then it shows the normal size of the
icon next to the `kind` and it looks kinda weird compared to the default
LazyVim icon.
