Output stderr when starting tsserver

Checklist

• [X] I have searched both open and closed issues and cannot find a duplicate.
• [ ] I can reproduce the problem with the latest version of the relevant packages.
• [ ] The problem still occurs after I issued M-x tide-restart-server in the buffer where I had the problem.
• [ ] I verified that the version and the configuration file path reported by M-x tide-verify-setup are correct.
• [ ] If tide is reporting an error or warning I think should not be reported, I can run tsc (and tslint, if applicable) without the error or warning I'm seeing in tide.
• [ ] If tide is not reporting an error or warning I think should be reported, tsc (or tslint, if applicable) reports the error or warning I was expecting to see.
• [X] I am positive the problem does not belong to typescript-mode or tsserver.

Relevant Version Numbers

• Tide: v5.1.3
• TypeScript: tsc --version Version 5.5.4
• Emacs: 29.4

Steps to Reproduce the Bug

Not a bug but I have done some debugging for errors very similar to https://github.com/ananthakumaran/tide/issues/438 and https://github.com/ananthakumaran/tide/issues/87.

Expected Behavior

When the tsserver process cannot start, it would be good to see why in the message buffer.

Actual Behavior

In many occasions this does happen.

I was able to get good output by setting this:

(set-process-sentinel process #'tide-net-sentinel)

In my case the error was:

Couldn’t locate project root folder with a tsconfig.json or jsconfig.json file. Using ’/home/user/.config/emacs/lib/tide/’ as project root.

At the point I kind of asked myself why that's the case and stumble across Emacs Async Processes page. It might be the case that start-process, being a wrapper, does not do much with regards to :stderr (see make-process).

I am not sure cause haven't tried (yet) but probably using make-process would give more control over the output and will end up showing the right message.
