External Libraries: Update the Requests library to version 2.0.6.

This is a maintenance release with minor changes:
* Fix typo in deprecation notice.
* Minor internal improvements for passing the correct type to function calls.
* Confirmed compatibility with PHP 8.2. No changes were needed, so Requests 2.0.1 and higher can be considered compatible with PHP 8.2.
* Various documentation improvements and other general housekeeping.

References:
* [https://github.com/WordPress/Requests/releases/tag/v2.0.6 Requests 2.0.6 release notes]
* [https://github.com/WordPress/Requests/compare/v2.0.5...v2.0.6 Full list of changes in Requests 2.0.6]

Follow-up to [54997], [55007], [55046], [55225], [55296].

Props jrf, costdev.
Fixes #58079.
