[New Server] Psalm

[JSteitz]

Which server would you like to request to be added?

• Server name: psalm
• Server homepage (e.g., GitHub page): https://psalm.dev/

Which languages does this server target?

• Languages: php

How is this server distributed?

• Is the server distributed through a standardized channel (such as release files, npm, pip, etc.)? (leave empty if unknown): composer
• Is this server added in lspconfig?: yes

Sorry for not creating a pull request, I just needed the server just now. The code would be:

-- init.lua
local installers = require "nvim-lsp-installer.installers"
local path = require "nvim-lsp-installer.path"
local server = require "nvim-lsp-installer.server"
local composer = require "nvim-lsp-installer.installers.composer"
local std = require "nvim-lsp-installer.installers.std"
local context = require "nvim-lsp-installer.installers.context"
local process = require "nvim-lsp-installer.process"

return function(name, root_dir)
    return server.Server:new {
        name = name,
        root_dir = root_dir,
        homepage = "https://psalm.dev/",
        languages = { "php" },
        installer = installers.when {
            unix = {
                std.git_clone "https://github.com/vimeo/psalm.git",
                composer.install(),
                context.receipt(function(receipt)
                    receipt:with_primary_source(receipt.git_remote "https://github.com/vimeo/psalm.git")
                end),
            },
        },
        default_options = {
            cmd_env = {
                PATH = process.extend_path { path.concat { root_dir, "bin" } },
            },
        },
    }
end

Hello! Cool! Pull requests are always very welcomed to add new servers. If the distribution of the server is simple, the installation will most likely be so as well (existing server installers may be used for reference!). Otherwise, @williamboman will get around to looking into this ASAP!
