Minor issues in Plasma 5.8 announcement

[Yuri Chornoivan]

Hi,

i18n() in headers is borken (unclosed quotation and parentheses). Examples:

plasma-5.8.0.php:47:
<h3><?php i18n("Desktop Widgets</h3>

plasma-5.8.0.php:58:
<h3><?php i18n("Get Hot New Stuff</h3>

etc. (lines 69, 77, 91, 101, 111, 112, 145, 158).

Unescaped address in <a> tag leads to the scripty's failure to extract string:

plasma-5.8.0.php:170:
<p><?php i18n("Now that <a href="https://dot.kde.org/2016/08/10/kdes-kirigami-ui-framework-gets-its-first-public-release">Kirigami</a>, our set of versatile 
cross-platform UI components, has been released, we’re pleased to bring you a 
revamped version of Plasma Discover based on Kirigami.");?></p>

Many thanks for your work and fixing these issues.

Best regards,
Yuri
