fix(template): Fix meta.canonical URL

[anthonyroussel]

https://raw.githubusercontent.com/jsonresume/resume-schema/master/resume.json is 404

Should be https://raw.githubusercontent.com/jsonresume/resume-schema/master/schema.json

Thanks!

I found it interesting why this happened because the sample json I based it upon is the one that resumed init gave me. So I've dug into it why this was wrong.

Turns out that the latest release of resume-schema is 1.0.0 and that release is like 3 years old. This is also used by resumed. In this version, the filename of the schema is actually resume.json. However, since 1.0.0 this filename has changed on master and therefore it doesn't exist anymore and this is why resumed gives a file with the wrong URL.

I will correct my samples here with your PR, but I will also forward reports upstream to the correct places.
