Showing the language icon in rendered code blocks

Feature description

The title says it all , something like python icon in MD rendering with markviews:

Personally I prefer them to be at the left, and only icon

Background:

If the concealer module is configured like :

    ["core.concealer"] = {
      config = {
        icons = {
          code_block = {
            conceal = true, -- Hide @code and @end code markers
          },
        },
      },
    },

The entire @code LANGUAGE .... @end is hidden. I find the @code and @end somehow noisy, polluting and repetitive, specially when reading the notes, but the Language type at least it's icon is informative and useful to keep visible while concealing the boiler plate @code...@end, a perfect granular configuration might look like :

```lua
    ["core.concealer"] = {
      config = {
        icons = {
          code_block = {
            conceal_header = true, -- Hide @code and @end code markers
            conceal_language_name = true, -- Hide language name ex : python
            conceal_language_icon = false, -- Hide language icon
            language_icon_position = left, -- "left", "right"
            icon_prefixe = "", -- anything to prefix the icon of language like ">" or any nerdfont like \uf121, manifesting the code block itself
          },
        },
      },
    },
