remove function wrapper around kubectl aliases

[cornfeedhobo]

This is minor house cleaning. I saw the function name and didn't like that it's name wasn't well scoped,
and further, I see no need for wrapping this logic with a function.

Thought for the future: maybe all alias loading should be wrapped in a callable with a predictable name?
e.g. _bash_it_load_alias_<alias plugin name>

Motivation and Context

I don't like polluting the global namespace with poorly named functions

How Has This Been Tested?

See the test output.

The lint test is broken because the test image no longer has brew baked in. There is probably some action we can add, and I'm happy to wait and rebase after that's finished.

Hiding whitespace shows that this change is simply removing the function wrapper as described.

In the absence of any comments stating why the wrapper might be useful in this case, removing it seems appropriate as its not standard bash-it practice.

For posterity, I'm going to rebase and push now that the CI job is fixed. Thanks again for taking care of that.

Edit: The CI job here is still using the old config and I don't know why. I'm going to close and re-open, or maybe open another branch to hopefully get Github to behave.
