Change default root direction and invalid 403 error pages

[EDIflyer]

I'm very impressed with YOURLS - have it setup running on Docker behind NPM and works brilliantly.

I understand that navigating to domain.tld or to domain.tld/invalidshortlink both show a 403 error page by design but I was wondering how to change them to direct to a customised page?

Root: Add an index.(php|html) file
Invalid shortlink: This redirects to the root by default.

YOURLS/yourls-go.php

Lines 25 to 27 in fd70f6d

	// Either reserved keyword, or no such keyword
	yourls_do_action( 'redirect_keyword_not_found', $keyword );
	yourls_redirect( YOURLS_SITE, 302 ); // no 404 to tell browser this might change, and also to not pollute logs

Plugins can override the behavior for unrecognized links, e.g. this one that fuzzy-suggests possible matches.

Fantastic, thanks @dgw
