Use of depracated functions

[KriBielinski]

The issue appears after loading nvim-cmp into Neovim with at least one source (for example: cmp-buffer).

If you then enter command :checkhealth 2 warnings appear:

• - WARNING vim.str_utfindex is deprecated. Feature will be removed in Nvim 1.0 - ADVICE: - use vim.str_utfindex(s, encoding, index, strict_indexing) instead.
• - WARNING vim.validate is deprecated. Feature will be removed in Nvim 1.0 - ADVICE: - use vim.validate(name, value, validator, optional_or_msg) instead.

It seems that this happens regardless of which source you use, but there needs to be at least one source.
I have Neovim v0.11.0 and use Lazy.nvim as plugin manager (although I am not sure whether this matters).

Seems like it might be an important issue as this plugin may stop working in the eventual Nvim 1.0 release.
