Deprecation warning for tbl_flatten

[low613]

Description

It seems that vim.tbl_flatten is going to be deprecated in Nvim0.13 and I am now getting a deprecation warning for it

- WARNING vim.tbl_flatten is deprecated. Feature will be removed in Nvim 0.13
  - ADVICE:
    - use vim.iter(…):flatten():totable() instead.
