Corrected Dublin Core Terms namespace

[Bobulous]

Modified namespace prefix from "dc" to "dct" within the span element for the title, to match the xmlns:dct declaration for the Dublin Core Terms namespace.

Description

Unless I'm misunderstanding the intent of the code, the span element for the title is trying to refer to the Dublin Core Terms "title" property, in which case I believe it should be referring to the "dct" namespace prefix declared within one of its ancestor elements.

Other information

The same thing is seen in LicenseCode.vue and I'll request a pull for a patch of that file too. (Apologies, I don't know how to get both changes included in the same patch using the web UI editing tool.)

Sorry, @akmadian, I couldn't find a recipe for proper submission of minor fixes. I'll raise an issue first in future, then refer to it from any related pull requests I create.
