Add bottle-song

[BNAndras]

See https://forum.exercism.org/t/add-bottle-song-exercise/15761/2.

This PR also deprecates Beer Song in favor of Bottle Song. The practice exercise generator script gave me blank files, but I was able to cobble together what I needed.

@BNAndras Could you try using: pwsh bin/add-practice-exercise.ps1 -d 3 -a erikschierboom bottle-song. That should give you a generator file. Note: before running the above script, please pull in the latest main first.

[BNAndras]

I pulled in the latest main, but that command didn't give me any different output from before. I see the empty files for the test suite, stub file, and example solution that configlet would give me normally, a filled-out csproj, a filled-out .editorconfig, and an updated Exercises.sln.

[ErikSchierboom]

Ah, I might have figured out the issue. I'll work on a fix.

[ErikSchierboom]

@BNAndras I'm hoping #2386 fixes it. Please rebase on the latest main

[BNAndras]

Yeah, I see generated tests now. 🎉

[ErikSchierboom]

I think it would help with readability to put the expected value in a variable:

Suggested change

	Assert.Equal({{ test.expected }}, {{ testedClass }}.{{ test.testedMethod }}({{ test.input.startBottles }}, {{ test.input.takeDown }}));
	string[] expected = [
	{{- for line in test.expected }}
	{{ line | string.literal }}{{- if !for.last }},{{ end -}}
	{{ end }}
	];
	Assert.Equal(expected, {{ testedClass }}.{{ test.testedMethod }}({{ test.input.startBottles }}, {{ test.input.takeDown }}));

[BNAndras]

I concur. Ideally, the expected value should span multiple lines for readability, but I’m not sure how that generator could handle that.

[BNAndras]

On second look, I think that's what the template is doing actually. I assumed ./bin-update-tests.ps1 bottle-song would regenerate the test suite using the updated generator template, but nothing happened for me after running that command.

[ErikSchierboom]

@BNAndras Looks good. I'm working on fixing the test runner properly, so I'll need to hold off on merging this until that is fixed.
