Use hyphens for bulleted lists

[kytrinyx]

We've had some churn due to not having documented our
preference.

This is now documented in
exercism/docs#399

Could you add the MD004 rule to this repo's markdownlint rules? Then CI should enforce that the PR is correct, and that future PRs do not add unordered list items with the less preferred style.

problem-specifications/.markdownlint.jsonc

Lines 1 to 6 in 7012a73

	// For information on writing markdownlint configuration see:
	// https://github.com/DavidAnson/markdownlint/blob/main/README.md#optionsconfig
	{
	"MD013": false, // Exercism tends to break lines at sentence ends rather than at a column limit
	"MD024": false // The format for instructions.md requires repeated headings, e.g. "Task"
	}

I believe:

     "MD004": "dash",

It's run from here:

problem-specifications/.github/workflows/ci.yml

@ee7 I updated the linter, and CI is passing. I'm going to deliberately cause it to fail, to check that it's configured correctly.

[kytrinyx]

Ok, that looks good. Thanks for your help @ee7

[ee7]

CI does look good - thanks for checking that it works.

I also checked independently that, with this PR, there really are no remaining unordered list items that use * or + (both are valid markers, but we only used * previously):

$ git rev-parse --short HEAD
b61cb4ac
$ rg -U '\n\s*[\*\+]{1}\s+' --type markdown
$ echo $?
1

What's not to love about a linting PR? 💛
