Dracula theme: Fix Kubernetes colors

[AlyxPractice]

Hello,

By default, the Kubernetes colors are displayed like so:

It's hard to read, and really bright, seeking for our attention. The purpose of displaying Kubernetes context is just to know where our kubectlcommands will run, so it's nice to know, but not a major information that should get all our attention in my opinion.

Or, what I suggest in this PR, use purple as it's less attention seeking:

Original version:

Version with darker text:

Suggested changes:

Tell me what you think :)

I've added k8s-context to bobthefish_display_colors to hopefully make this less likely to happen in the future?
