chore: remove pyls and pyls_ms

[mjlbach]

• pyls is unmaintained and has been continued as a community fork, pylsp
• pyls_ms has been abandoned by microsoft in favor of the proprietary
  pylance/the less featureful (but open-source) pyright

If you really want these in your config for whatever reason, just copy/paste the configs as such (please don't):

 [[
https://github.com/palantir/python-language-server
`python-language-server`, a language server for Python.
The language server can be installed via `pipx install 'python-language-server[all]'`.
 ]]

require('lspconfig').pyls.setup {
    cmd = { 'pyls' },
    filetypes = { 'python' },
    root_dir = function(fname)
      return vim.fn.getcwd()
    end,
}

local util = require 'lspconfig/util'

[[
https://github.com/Microsoft/python-language-server
`python-language-server`, a language server for Python.
Requires [.NET Core](https://docs.microsoft.com/en-us/dotnet/core/tools/dotnet-install-script) to run. On Linux or macOS:

curl -L https://dot.net/v1/dotnet-install.sh | sh

`python-language-server` can be installed via [build](https://github.com/microsoft/python-language-server/blob/master/CONTRIBUTING.md#setup).
Set cmd to point to `Microsoft.Python.languageServer.dll`.

cmd = { "dotnet", "exec", "path/to/Microsoft.Python.languageServer.dll" };

If the `python` interpreter is not in your PATH environment variable, set the `InterpreterPath` and `Version` properties accordingly.

InterpreterPath = "path/to/python",
Version = "3.8"

This server accepts configuration via the `settings` key.

require('lspconfig').pyls_ms.setup {
    filetypes = { 'python' },
    root_dir = function(fname)
      return util.find_git_ancestor(fname) or vim.loop.os_homedir()
    end,
    settings = {
      python = {
        analysis = {
          errors = {},
          info = {},
          disabled = {},
        },
      },
    },
    init_options = {
      interpreter = {
        properties = {
          InterpreterPath = '',
          Version = '',
        },
      },
      displayOptions = {},
      analysisUpdates = true,
      asyncStartup = true,
    },
  },
}

The CONFIG.md still includes those, would you appreciate a contribution to remove it?
Never mind, I seem to have looked at an old state.
