Edit button in docs broken after r96

[moraxy]

Description of the problem

#14846 stripped the localization from the [path] placeholder to get the links to the source files working again but the edit button in the top right needed that to point to the localized docs file.

three.js/docs/page.js

Lines 102 to 106 in 12450be

	button.addEventListener( 'click', function ( event ) {
	window.open( 'https://github.com/mrdoob/three.js/blob/dev/docs/' + section + '/' + path + '.html' );
	}, false );

First noticed in #14750 (comment) as far as I can tell. A previous hotfix(hiding the button) was applied in 0c58464, but got removed with the release of r96.

A simple fix is to add the following line in page.js right before window.open().

if ( section === 'api' ) path = /\/api\/[A-z0-9\/]+/.exec( pathname ).toString().substr( 5 );

three.js/docs/page.js

Line 104 in c0dbf05

window.open( 'https://github.com/mrdoob/three.js/blob/dev/docs/' + section + '/' + path + '.html' );

This should ensure that the path has the localized part which is necessary to build the correct URL.

Any better ideas? 😇
