WP-CLI error when Page Cache is Disabled

[apkdesign]

Description

When Page Cache is turned off in the SpinupWP UI, and you try to use the "wp spinupwp cache purge-site" command you will get the below error message:
Error: 'cache' is not a registered subcommand of 'spinupwp'. See 'wp help spinupwp' for available subcommands.

wp spinupwp status
Page Cache: Disabled
Object Cache: Enabled

If you enable Page Cache again and run the command, it will work:

wp spinupwp status
Page Cache: Enabled
Object Cache: Enabled

wp spinupwp cache purge-site
Success: The page cache was purged.

Tested on the latest SpinupWP Plugin version 1.7.1 and the previous two versions.

Expected behaviour

Return an error message that "Page Cache is turned off and is unable to purge site-cache"
