Update package_manager.api.php to document an assumption

As discussed earlier today: the maintenance mode check could and should be done in a validator.

Other than that: 👏 Yes, please! 😊

One question other than that looks good!

Created 📌 [PP-1] Create a validator to check if site is in maintenance mode while package manager is in use. Postponed , should we block this issue on it ?

I think, as we are going to check that in a validator now, we don't assume that anymore it's explicitly checked. So we should remove the assumption of maintenance mode from package_manager.api?

Also, we don't need to block this issue on 📌 [PP-1] Create a validator to check if site is in maintenance mode while package manager is in use. Postponed .
If this sounds good to you, can assign this to @tedbow for further review, it looks good to me.

Only one of the two things mentioned in the issue summary are in the merge request?

#15: so the issue summary is outdated then? Are we planning to do that in another issue? Where is that issue?
