support client config with tcp_port but without command

#2214

I have no idea if this is too hacky to be pulled, or what it breaks. It does work for my usecase tho. Would be cool if it doesn't find a server, it would just wait until one shows up instead of disabling the lsp until manually enabled again. Maybe i'll do it if I find it annoying enough.

If there would be small edits needed to be pulled I can totally do them, if there are fundamental issues I probably wont bother.

We should mention this new behavior in documentation (in the docs folder). Currently it states that we start the server - https://lsp.sublimetext.io/client_configuration/#tcp-localhost-subprocess-acts-as-a-tcp-server

Thanks for detailed feedback, tried to fix it all, the way I pass the stderr argument to the constructor looks filthy but no idea what is correct form to do this so I just kept it simple and ugly.

the linter stuff should be fixed, no idea what the macos error is about

edit: also, should we update the gdscript server setup howto in the docs to command-less version ? Or mention it there as an fix for the specific issue I was having

thanks for putting up with my mess, do you use any specific stuff for the formatting? black? or am i missing something in the pylsp/pyright that i have in sublime.

I'm just following the conventions that we have in this code base and the changes were all manual.
