Docker command in README doesn't quite work out of the box

[notnarb]

Context: Using Fedora Silverblue 42 + Podman. This issue may be Podman specific

Describe the bug

Using the Docker command in the README (ref):

docker run -it quay.io/redhat-developer/yaml-language-server:latest

The server doesn't appear to work as expected, ignoring SIGINT/SIGTERM and crashing soon after startup when started using emacs lsp-mode.

With a clue from #1012 I discovered that adding --pid=host seems to fix the issue 👍

Other flyby suggestions:

• I think the -t command is unnecessary because you don't normally use a TTY to interact with a language server
• maybe throwing in an --rm might be beneficial for users as this isn't a stateful container.

Saving the following as yaml-language-server in my $PATH appears to work as expected.

#!/bin/bash
