zlib: there are constants documented that don't exist

[jasnell]

In the zlib docs, there are a handful of constants listed that do not exist in the actual code:

Specifically:

• zlib.Z_BINARY
• zlib.Z_TEXT
• zlib.Z_ASCII
• zlib.Z_UNKNOWN

See: https://nodejs.org/dist/latest-v6.x/docs/api/zlib.html#zlib_constants

Removed in: #7203

We would just need to remove these from docs right?

It seems like the .md file is already up-to-date. Are the HTML files not updated automatically?

Ah that sounds right. The constants refactor commits have not yet made it into a release.

However, those commits are marked as semver-major (via a label) and will not land in v6: #7203, but the "head: docs come from v6 currently.

@fhinkel Could you check the v6.x branch, and if they are still there but not in the code, open a PR against that branch? :D
