DX Github link is double-escaped

[ryanmurakami]

The link to Github at the bottom of the "CLI Autocomplete" section in the most recent 1.15 blog post double-escapes the encoded characters and ends up going to the default Issues page.

The url currently in the page is this: https://github.com/serverless/serverless/issues?utf8=%E2%9C%93&q=is%253Aissue%20is%253Aopen%20DX%253A%20

But should be this: https://github.com/serverless/serverless/issues?utf8=%E2%9C%93&q=is%3Aissue%20is%3Aopen%20DX%3A%20

I don't think there's an easy way to fix this in the post (I tried by the spaces in the query kill the markdown url). This would probably need to be changed in whatever is rendering the markdown for the site.
