Improves accessibility of the "Copy this section" button and "Return to Top" link:
- uses `setTimeout()` and `clearTimeout()` to properly handle the "Copied!" text
- simplifies the button text by removing the redundant visually hidden text
- fixes the mismatching visual and DOM order of the Copy button and the "Return to Top" link
- improves the "Return to Top" links by providing real page fragment identifiers, when possible
- hides the "Return to Top" up arrow from assistive technologies
- minor coding standards

Per WCAG 2.0 guidelines, big chunks of italic text should be avoided for better accessibility.
Additionally, replace the legacy `.error` class for "You deactivated this plugin and may no longer need this policy" message with `.notice-info`.
Follow-up to [47147], [48116].

* Add missing translator comments.
* Fix placement of some translator comments. Translator comments should be on the line directly above the line containing the translation function call for optimal compatibility with various `.pot` file generation tools. The CS auto-fixing, which changed some inconsistent function calls to multi-line function calls, is part of the reason why this was no longer the case for a select group of translator comments.
Includes minor code layout fixes.
Polyglots, rejoice! All WordPress core files now have translator comments for all strings with placeholders!
