Add support to pylsp

[martini97]

I get some warnings about pyls being deprecated:

Warning (emacs): The palantir python-language-server (pyls) is unmaintained; a maintained fork is the python-lsp-server (pylsp) project; you can install it with pip via: pip install python-lsp-server Disable showing Disable logging

It would be nice to add support to the pylsp server as well, so far I got it working with:

(use-package lsp-docker
  :straight t
  :config
  (defvar lsp-docker-client-packages
    '(lsp-css lsp-clients lsp-bash lsp-go lsp-html lsp-pylsp ;; lsp-pyls
	      lsp-dockerfile lsp-javascript lsp-terraform))

  (setq lsp-docker-client-configs
	'((:server-id bash-ls :docker-server-id bashls-docker :server-command "bash-language-server start")
	  (:server-id css-ls :docker-server-id cssls-docker :server-command "css-languageserver --stdio")
	  (:server-id dockerfile-ls :docker-server-id dockerfilels-docker :server-command "docker-langserver --stdio")
	  (:server-id gopls :docker-server-id gopls-docker :server-command "gopls")
	  (:server-id html-ls :docker-server-id htmls-docker :server-command "html-languageserver --stdio")
	  ;; (:server-id pyls :docker-server-id pyls-docker :server-command "pyls")
	  (:server-id pylsp :docker-server-id pylsp-docker :server-command "pylsp" :docker-image-id "martini97/lsp-docker-langservers" :docker-container-name "martini97-lsp-pylsp")
	  (:server-id ts-ls :docker-server-id tsls-docker :server-command "typescript-language-server --stdio")))

  (let ((projects-dir (expand-file-name "~/Projects")))
    (lsp-docker-init-clients
      :path-mappings `((,projects-dir . "/projects"))
      :client-packages lsp-docker-client-packages
      :client-configs lsp-docker-client-configs)))

On my Emacs config and using this Docker image:

# Local Variables:
# docker-image-name: "martini97/lsp-docker-langservers"
# End:

FROM emacslsp/lsp-docker-langservers

RUN pip3 install 'python-lsp-server[all]'

But it would be nice to have it added to the package.
