Improving jsonContentType Regex

• Title adequately and concisely reflects the feature or the bug

I was getting a PR ready for this, but it said to discuss via Issues first, so here I am. I'm pretty sure this is a good fix, but let me know if I am wrong.

Original:
jsonContentType: new RegExp('^application/[a-zA-Z.]+\\+json') (Link)
My proposed change:
jsonContentType: new RegExp('^application/[a-z0-9.]+\\+json$', 'i')

The original expression was incorrect because it was not checking 0-9, so a valid Content-Type like this would not validate: application/vnd.Microsoft.IIS.Administration.Files.2.2.0+json

Also added the ending $ for completion, and replaced A-Z with the i flag to account for mixed case letters, and also the possibility of mixed case throughout the entire Content-Type.

Are you willing and able to fix this?

Yes
