The HTML specification states that link type keywords like 'nofollow'
are ASCII case-insensitive. Sites using rel="NoFollow" or rel="NOFOLLOW"
were incorrectly treated as follow links, causing Scrapy to crawl pages
it should skip.
Fix: add .lower() before the token split so all casing variants of
'nofollow' are correctly recognized.

* Add support for HTTP/2 and SOCKS proxies to HttpxDownloadHandler.
* Update the docs.
* Trim the tables.
* Restore lost wording.
* Handlers docs improvements and fixes.
* Allow configuring the log level of the retry give-up message
The "Gave up retrying ..." message was always logged at ERROR, which
inflates the log_count/ERROR stat even when giving up on a request is
expected (e.g. broad crawls hitting dead hosts).
Add a RETRY_GIVE_UP_LOG_LEVEL setting, a give_up_log_level argument to
get_retry_request(), and a give_up_log_level request meta key to override
it per request. The value accepts a level name ("WARNING") or number
(logging.WARNING). The default ("ERROR") preserves the previous behaviour.
Fixes#5297, fixes#4622

* Address Adrian's review feedback: simplify and reorganize docs
- Move give_up_log_level reqmeta section before max_retry_times (alphabetical order)
- Simplify give_up_log_level section in request-response.rst (brief, links to setting)
- Simplify RETRY_GIVE_UP_LOG_LEVEL setting docs in downloader-middleware.rst
- Change 'When initialized' to 'When set' in max_retry_times section
- Docs now follow pattern of linking to complementary setting/meta key rather than duplicating information
Per Adrian's feedback: keep docs concise and cross-link setting ↔ meta key
* Address Adrian's code review feedback on RETRY_GIVE_UP_LOG_LEVEL feature
- Fix alphabetical ordering of give_up_log_level in request-response.rst
- Remove circular references: change 'see X for details' to 'see also X' pattern
- Simplify docstring for give_up_log_level parameter (4 lines → 2 lines)
- Update test domains from www.scrapytest.org to example.com
* Apply suggestion from @AdrianAtZyte
* Minor changes
* Fix example formatting.
