fix add-zsh-hook not found

[veggiemonk]

I had the following error

.oh-my-zsh/custom/plugins/almostontop/almostontop.plugin.zsh:16: command not found: add-zsh-hook

After adding the test, everything is fine now.

By the way, this plugin rocks!!!! I was looking for something like that in a looooong time because I always end up writing at the bottom of the screen and this is not very ergonomic... Really hurt the back and the neck...
Thank you for this plugin!!!

Hey @veggiemonk, really appreciate the feedback! Thanks!
About the PR: Don't want to rely on the specific path to enable the hook, seems like there is something more reliable. Since I'm not quite experienced in zsh stuff, I've just added autoload for the hook as a default behaviour.

Thanks @Valiev, your solution is better.
