Add better support for PyCharm

PyCharm's tailwindcss plugin has an issue with the CLI.

It might be a handy idea to support a workaround that is handled by the runserver and runserver_plus command. Say could temporarily create the required files and links and delete them, when the server exits.

The idea with the runserver command is not good. I kills the support as soon as the runserver is not running. The approach has to be to create a management command, that installs the fix based on the used tailwindcss cli version.

And the fix should integrate a way to update the links as soon as the cli version is changed.

Version 2.21.0 includes support for the new subcommands install_pycharm_workaround and remove_pycharm_workaround.
