Fix potential issue with cmp

I won't be much appreciated with this PR. It's fine to not merge it. But In my opinion this issue raise a valid concern, however I'm still learning lua/nvim, I only have a limited knowledge, so take this PR with a grain of salt. Until this PR https://github.com/NvChad/ui/pull/382, the plugin couldn't be used at all with [NvChad](https://nvchad.com/) Now, it's working, but with some limitations. There is two issues: First one was an unexpected kind (this one is fixed) The second is still a remaining issue related to NvChad because it creates an invalid `menu_hl_group` since there's a concatenation of the name: https://github.com/NvChad/ui/blob/cfafe4aeb7b5d7ffde097d3d8df61289e33a6d51/lua/nvchad/cmp/init.lua#L15 So, depending of cmp style we choose in NvChad, it may crash nvim. I assume by convention it should be name the same `CmpItemKind%KIND_NAME%` : https://github.com/hrsh7th/nvim-cmp/blob/29fb4854573355792df9e156cb779f0d31308796/doc/cmp.txt#L403-L408 > *CmpItemKind%KIND_NAME%* Highlight group for the kind of the field for a specific `lsp.CompletionItemKind`. If you only want to overwrite the `method` kind's highlight group, you can do this: >vim highlight CmpItemKindMethod guibg=NONE guifg=Orange < Also, there's an aesthetic reason: cmp is highly customizable and it can offer customization for the users. In it's current state, it's a bit strange to see the icon on the right, meanwhile all other icons are on the left.  Take against this PR: - Now it will look ugly by default in CMP and you will have to configure the icon yourself - The icon should be added to the pre-configured nvim such has NvChad (author is ok to add `BladeNav` icon), possibly (Lazyvim?) - I can make my own fork if I'm not happy with the default icon (and that's fine) :laughing:
