fix(aliasing): don't alias apis (to api)

[silasbw]

/api is an endpoint, so we shouldn't alias /apis to /api.

Fixes #391

@silasbw This might need a slightly bigger callout in the CHANGELOG, or a deprecation notice with console.warn. I recently ran into this issue:

• Docker for Mac has a /apis/v1 path implemented in its proprietary version of Kubernetes
• Official Kubernetes does not
• We upgraded to kubernetes-client 6.8. It worked hunky-dory against Docker for Mac
• It crashed when we pushed out to AWS, where it talked to a real Kubernetes instance
• I made a quick trip to the CHANGELOG
• Ended up here

Our line of code was this:

this.client.apis.v1

and now it's without the 's.' It crashed with cannot access v1 of undefined blah blah blah you're a javascript developer this is your life.

Anyway, thanks for the library, it's been very good to us otherwise. :)

Oh no! I'm sorry about that and you're right: I should have deprecated/warned this and made this a breaking change / major version bump. Thanks for the feedback and I'll adjust my process for similar changes going forward.

For this specific issue, I can try to get something in place to prevent others from hitting the gotcha you ran into. Thanks again.
