Language servers fail if one is missing

[QaidVoid]

Summary

If one of the language server from language-servers list is missing, none of the language servers work.

Reproduction Steps

Configure multiple language servers

~/.config/helix/languages.toml

[[language]]
name = "jsx"
auto-format = true
language-servers = ["typescript-language-server", "biome", "emmet"]
formatter = { command = "biome", args = ["format", "--stdin-file-path", "test.jsx"]}

Expected behavior:
The existing language server should work even if other language servers are missing.

What happened:
The language server process is spawned but it doesn't work.

I also faced this problem. This is fixed here #7900, specifically in this commit 1bd0410. Although it is not yet merged.

We might want to extract that fix to a seperate pr so we can get it into the coming release

[woojiq]

Sure, do this?

I think we want both changes from #7900 anyways but I agree - could you pull that commit out to a separate PR? It's pretty distinct from the pull diagnostics changes and I'd prefer to have those be cleanly separate in the commit history
