Update generic node removal documentation to schedule a drain when removing worker nodes

No description provided.

The current changes generate a lot of unnecessary content for the storage node how-tos. We never need to schedule a storage node drain for the next maintenance, so there's no point in including all that text in those how-tos.

I don't think the commas here are correct in English, but I always trip over comma rules

[HappyTetrahedron]

Normally you don't use commas after "first", "second" etc. but in the context of a list of things you use them anyway. The exception to the rule.

Though I guess since this is a bullet list you could consider each bullet point a standalone sentence and skip the comma... Huh. Guess it's a special case.
(The comma would be needed if all these sentences came one-after-the-other in the same paragraph)

I guess that's what confused me when reviewing. I don't have hard feelings either way, but I'm still mentally stumbling over the commas in the bullet list.

This tip isn't needed for the scheduling case

Suggested change

	+
	ifeval::["{cloud_provider}" == "cloudscale"]
	ifeval::["{delete-node-type}" == "storage"]
	[TIP]
	====
	On cloudscale.ch, we configure Rook Ceph to setup the OSDs in "portable" mode.
	This configuration enables OSDs to be scheduled on any storage node.
	With this configuration, we don't have to migrate OSDs hosted on the old node(s) manually.
	Instead, draining a node will cause any OSDs hosted on that node to be rescheduled on other storage nodes.
