v1.17.5: tool upgrades, disable http/2 when needed, blackfire upgrade

Most of what you want to know is in the v1.17.0 release notes so please check there... Make sure you read the Caveats.

Installation/Upgrade

See the installation instructions for details, but it's easy:

• macOS Homebrew and Linux Linuxbrew: brew install drud/ddev/ddev or brew upgrade drud/ddev/ddev ). (You may need a brew update for homebrew to find the new release.). This works on Apple Silicon Homebrew as well.
• Windows: Use choco upgrade -y ddev --version 1.17.5 to get this one, or download the ddev_windows_installer below.
• Linux and macOS with the install_ddev.sh script: Download the script, make it executable, and run it: ./install_ddev.sh or curl -LO https://raw.githubusercontent.com/drud/ddev/master/scripts/install_ddev.sh && bash install_ddev.sh
• And anywhere, you can just download the tarball or zipball, untar or unzip it, and place the executable in your path where it belongs.
• Consider ddev delete images after upgrading to free up disk space used by previous docker image versions. This does no harm.
• In the past, a ddev poweroff was required; now ddev itself detects that you have a new version and asks for permission to do a poweroff.

Key changes for v1.17.5

This release has a number of minor upgrades:

• Please see the v1.17.0 release notes of course.
• Update default composer 2 in web container and ddev composer to 2.1.1
• Update wp-cli to v2.5.0 (first wp-cli release in a long time)
• Allow globally disabling http/2 support in ddev-router (ddev config global --disable-http2)
• Minor increases of webserver buffer sizes in ddev-router and ddev-webserver to help with huge cookie payloads.
• Upgrade to Blackfire agent v2 in web container, removing deprecation warnings.
• Quite a lot of upgrades to infrastructure and cost reduction work, moving tests to GitHub Actions, etc.

Caveats

• This contains composer 2.1.1. There was a reported issue with composer 2.1.0 and composer-patches, cweagans/composer-patches#363. If you need to lock composer to an earlier version (or update to a later version) you can do that in .ddev/config.yaml with and explicit composer_version: 2.0.14 for example.
• Please see the Caveats in v1.17.0 release notes.
