Editorial: Make pageshow.persisted non-normative refer to salvageable…

[nyaxt]

Editorial change - skipping the checklist template.

This is an editorial change which attempts to remove the unsalvageable normative text which I was confused when I was reading through it. We now have the #concept-document-salvageable, so this PR attempts to replace the enumerated conditions with its reference.

Open Question:

• The removed list contained "Active WebSocket Objects" condition. I couldn't find a normative step that "sets salvageable state to false". Should we also make the change?

Hmm, I wonder if we should keep the list. It's kinda nice to have a list of things in the note instead of having to go through the reference. Referring to the "salvageable" concept instead of using "unsalvageable" sounds good though.

The WebSockets bit is specified here, but there's an open issue about it: #1931

Thanks for the pointer for the WebSockets bit - I missed it.
I'll update the PR to keep the list.

@rakina I addressed your comment. PTAL

Thanks, this looks like a nice editorial change. I have some suggestions to make it even more readable, and probably @domenic needs to review this too (for the write access bit?)

LGTM, thanks!
