Adding support for erb-lint by Shopify

Name: erb-lint
URL: https://github.com/Shopify/erb-lint

There is this issue open on the Ale's repository. I am curious is this possible to add this here?

I was trying around and thought I might be able to change the lintingCommand and formatCommand to get it work. But I am not really sure what that two commands are expecting. Would love some input on whether this integration is possible.

This gets close, I'm still having some weirdness with erblint writing random configs to disk with this setup, still looking into that.

local capabilities = require("cmp_nvim_lsp").default_capabilities(vim.lsp.protocol.make_client_capabilities())
local erblint = {
    lintCommand = "erblint --format compact --stdin ${INPUT}",
    lintStdin = true,
    lintFormats = {
      "%f:%l:%c: %m",
    },
    lintIgnoreExitCode = true,
    formatCommand = "erblint --autocorrect --stdin ${INPUT} | tail -n +5",
    formatStdin = true,
}
lspconfig.efm.setup {
    capabilities = capabilities,
    init_options = { documentFormatting = true },
    settings = {
        rootMarkers = {".git/"},
        languages = {
            eruby = {erblint},
        }
    },
    filetypes = {
        "eruby",
    }
}
