Fix only replacing wildcard at end in toNamespace

[Anoesj]

The docs state that, when running debug.disable(), it will return the namespaces currently enabled and skipped. They are, however, often malformed. This seems to be because the toNamespace method only replaces a trailing *.

debug.enable('api:*,-*:verbose,-api:*:verbose');
const prevConfig = debug.disable();
console.log(prevConfig); // -> api:*,-.*?:verbose,-api:.*?:verbose

console.log(prevConfig); should have returned api:*,-*:verbose,-api:*:verbose.

The issue seems to be fixed by removing the $ in the replace regexp in toNamespace.

It might be nice to improve the following test too:

describe('rebuild namespaces string (disable)', () => {
	it('handle names, skips, and wildcards', () => {
		debug.enable('test,abc*,-abc');
		const namespaces = debug.disable();
		assert.deepStrictEqual(namespaces, 'test,abc*,-abc');
		// ^ could use more tests, maybe: *,test,-test,abc*,*abc,abc:*:xyz,-abc:*:xyz,-*:verbose (etcetera)
	});
	// ...
});

However, for the sake of keeping this PR clean, I haven't added that to this PR.

I think you need to set the regex to match globally, i.e. /\.\*\?/g, for the case like '*name*'

I wonder how to get the maintainer's attention to get contribution merged in?

I'm always looking, the project is currently blocked due to Node feature parity issues when moving from CJS to ESM. Please see the roadmap pinned on the repo.

Further, .enable() and .disable() have a ton of issues as it stands and need to be rethought/reworked entirely.
