Panic: runtime error with Krew

[a-mazed]

Hi!
Thank you for such a good tool!

I found an panic error when use Krew:

k krew version
panic: runtime error: index out of range [1] with length 1

goroutine 18 [running]:
github.com/dty1er/kubecolor/printer.(*VersionPrinter).Print(0xc000014088, 0x5400c0, 0xc0000ac028, 0x5400e0, 0xc0000ac008)

It should be:

k krew version
OPTION            VALUE
GitTag            v0.4.0
GitCommit         8bebb56

kubectl version

k version

Please check

It reproduced. Will fix it soon, thank you for the report

I fixed the crash by v0.0.19. Please update kubecolor and try again.

Because I wanted to avoid the panic quickly, so for now krew version is not colorized but I'll consider if I should do that.

Anyway thank you for opening the issue!
