Embedded Code Snippets - link is case sensitive.

[matt-forster]

I found something while I was trying to get links copied over from VSCode (copy as -> copy remote file URL) to render in my comments.

When linking a code snippet, whether or not the embedded code is rendered is actually dependent on the capitalization of the URL. Its important to note that both the user/organization and repo name have to match case for the embed to work.

Demonstrated by this issue: matt-forster/Code-Snippet-Repro#1

Feature described here: https://github.blog/2017-08-15-introducing-embedded-code-snippets/

It would be awesome to see case-insensitivity here, as it would increase the number of snippets that are embedded!
