FR: set showConstraintMessages to true when stringifing validation errors

[mjpieters]

Minor nit: Please set the showConstraintMessages parameter to ValidationError.toString() to true when validating headers, here:

webpack-userscript/lib/features/validate-headers/impl.ts

Lines 54 to 56 in 5bca4c8

	if (errors.length > 0) {
	throw new Error(errors.map((err) => err.toString()).join('\n'));
	}

If you use err.toString(undefined, undefined, undefined, true) there then the validator message is shown rather than the name, which is a bit more informative. Compare

- property updateURL has failed the following constraints: isUrl 

with

- property updateURL has failed the following constraints: updateURL must be a URL address

I'd have expected the issue to be closed automatically, because my PR referenced it with 'fixes'.

But, given that it was merged into the dev branch, perhaps you wanted to keep this open until it has been released?

Don't worry about closing this issue or not, I'll ensure it closed after it is released.

There will be a few more minor features along with this one in the next minor update.

Released in v3.2.0.
