"Check for Updates" feature appears to not work

[rocketeerbkw]

Describe the bug
While trying to reproduce some other errors, I noticed that I can't get the code path that checks for newer versions of lagoon-cli to execute. I'm not sure under what circumstances this check should run.

Additional context
The update check is performed in the PersistentPreRun of the root command, which I understood to be "run before all commands."

Reading the Cobra docs, it says:

The Persistent*Run functions will be inherited by children if they do not declare their own.

Since almost all of the commands have their own pre-run hooks, I think the root update check is never being called.

I'm ok with removing the update check entirely.
