Point "Report a Bug" link to github

[nikic]

This creates an empty issue with the following body:

From manual page: https://php.net/$id

@nikic, doc-ru and doc-tr have enabled issues too.
Maybe use the lang-depended "report a bug" link and English as default?

e.g.

$issuesEnabled = ['ru', 'tr'];
$bugsUrl = 'https://github.com/php/doc-' . (in_array($repo, $issuesEnabled, true) ? $repo :  'en') . '/issues/new?body=' . urlencode("From manual page: https://php.net/$id\n---\n");

In this case we should enable issues for all doc repos, the French one doesn't have them enabled as of yet.

@saundefined I think the key question is, when somebody clicks "Report a Bug" on a translated page, how often do they want to report an error in the content (that they just happen to see in a translated version) vs how often do they want to report a translation mistake.

I think it may make more sense to point everything at doc-en and then move issues to translations if they really are about translations only.
