[php-src] Issue #10272: Latest intl and icu versions cause "breaking change" with Canadian currency display

Issue: https://github.com/php/php-src/issues/10272 Author: victorjkhalaf ### Description The following code: ```php <?php $foreignCurrency = new NumberFormatter('en\_CA', NumberFormatter::**CURRENCY**); $foreignCurrency->setAttribute(NumberFormatter::**FRACTION\_DIGITS**, 2); echo $foreignCurrency->formatCurrency(109.99, 'CAD'); ``` Resulted in this output: ``` CA$109.99 ``` But I expected this output instead: ``` $109.99 ``` We recently tried to bump up our php Alpine Linux Docker image to 8.2 and this change seems to have been introduced with the intl extension, specifically NumberFormatter's formatCurrency call. I dug into it pretty deeply as I could not find ANY posts or changelogs on PHP itself relating to this. It SEEMS to be related to an update to the C ICU and CLDR libraries which, as I understand it, are what the intl extension uses underneath to format numbers. The ICU version I had when we ran Alpine 3.15 with php8.1 packages was 69.1 (identified via php -i under the Internationalization section), while 3.16 with php8.2 uses 71.0. That's when CLDR version 40+ was included based on the ICU github release notes. I was able to find this info as well which hinted at possible changes. https://github.com/unicode-org/cldr/pull/2366/files and specifically this comment https://github.com/unicode-org/cldr/pull/2366#discussion_r977849111 The issue of course is this breaks our own implementation where we append the CAD suffix to prices to identify CAD currencies. I'm trying to figure out if there's a way to NOT include the alpha before the symbol, but searching for how to write patterns reveals that the ¤ symbol in the pattern for en_CA (¤#,##0.00) is what shows the dollar sign, as well as the alpha for Canadian locales. We could just adapt our code and move to this standard, which is what I am leaning more on doing. I just wanted to report this because it seems virtually no source online besides my one Reddit post on PHPHelp mentions it. It's not so much a bug, I suppose, but it definitely is an unexpected behaviour change. I understand the PHP maintainers may not be able to do anything about it since it's done by the underlying C lib, but I wonder about documenting this at least? ### PHP Version PHP 8.2.0 ### Operating System Alpine 3.16
