refactor: Rename clang_format to clang-format

[tsakirist]

Scope

This makes the formatter name consistent with the executable and also with other tools like e.g. Mason, for better interoperability.

Why

One use-case is to be able to automatically install formatters that are registered with other tools like Mason.

local registered_formatters = require("conform").list_all_formatters()
for _, formatter in ipairs(registered_formatters) do
   MasonInstall(formatter) -- Asume a MasonInstall function exists
end

Sure, seems fine to me

nope, it isn't fine @stevearc
try to customize formatter)

require("conform").formatters.clang-format = {
prepend_args = {"--style", "{ BasedOnStyle: LLVM, IndentWidth: 4 }"},
}

prepend_args = {"--style", "{ BasedOnStyle: LLVM, IndentWidth: 4 }"},
}

You can index the formatters table with:
require("conform").formatters["clang-format"] = { prepend_args = {"--style", "{ BasedOnStyle: LLVM, IndentWidth: 4 }"} }

I'm not that good at lua, I think it should be mentioned somewhere for people like me
