Utilize ShellName and Add Test to Enable Completions W/out Shell on Unix #48918
Conversation
I confirmed the proposal by Kalle, dotnet#48420 that the shellMap that gets provided is a default list of shell names like "fish" or "zsh" that are stored in the Shell Env Var. They are all lowercase in the shell map.

Pull Request Overview
This PR aims to enable static completions to work in scenarios where a shell has not been specified on Unix by leveraging a default mapping of lowercase shell names. Key changes include:
- Adding a test (ShellDiscoveryTests.cs) to validate that the completions command works without an explicit shell.
- Updating CompletionsCommand.cs to convert the shell name to lowercase before lookup in the shell map.

maybe parameterize this test with the shell names and set the SHELL env var before each run so we can easily test all of our shell experiences??

That's a great point -- I think this test should be ok since it works in general on any generic shell. If we had more capacity I would probably add this to the test, but not going to prioritize it right now. Thank you for reviewing
