Support vendor media types (allow periods in application/*+json)

[glen-84]

Without this, the following media types are not accepted:

• application/vnd.github+json
• application/vnd.github.v3+json
• application/vnd.github.v3.raw+json
• application/vnd.github.v3.text+json
• application/vnd.github.v3.html+json
• application/vnd.github.v3.full+json

Something is still causing response bodies to be empty. I have to go AFK for a while, but I'll look into this later tonight or tomorrow.

Thank you for your contribution! 👍

This change looks good to me.
However, if you change the functionality, please add the test pattern at the same pull request.

@horiuchi,

I've added a test. I wasn't able to run the tests locally, as they don't appear to run correctly on Windows (possibly related to EOL characters). However, it seems to be passing.

Unrelated: Shouldn't this be node_modules (plural)?

[horiuchi]

Thank you for adding the unit test. It seems to have passed the test.
I do not have a Windows environment, so please let me know if there are any problems.

Thank you!
