Describe the feature

Currently, conform.nvim provides a highly convenient format_on_save option.

I propose adding a configuration option to conform.nvim that allows users to specify a list of LSP Code Action Kinds to be executed immediately prior to or during the format_on_save process. This feature would align with a common functionality found in popular editors, such as VS Code's "Code Actions on Save".

require("conform").setup({
  format_on_save = {
    -- These options will be passed to conform.format()
    timeout_ms = 500,
    lsp_format = "fallback",
    code_actions = { "source.organizeImports", "source.fixAll" }, -- ← new!
  },
})
