Add support for composer-plugin-api v2

[Ayesh]

Composer version 2 has composer-plugin-api version 2, and this plugin attemts to support both API versions.

See What's new in Composer 2 and UPGRADE-2.0 for more changes in API.

• Empty methods \Symfony\Thanks\Thanks::deactivate() and \Symfony\Thanks\Thanks::uninstall() are added to make it compatible both versions.
• On Composer v2, \Hirak\Prestissimo\CurlRemoteFilesystem is not used in favor of Composer's native \Composer\Util\HttpDownloader which make multiple Curl connections.

Related: #84 and composer/composer#8726.

thanks 🙏

Thanks for working on this :)

Due to internal changes in the package downloading components, we cannot support both composer-plugin-api v1 and v2 in the same package.

Is there really nothing we can do? What are the exact blockers?

Thanks for the quick reply @nicolas-grekas :)

Composer v2 has a HttpDownloader class that is not available in v1. However, we have access to the Composer object and its version, so I will work on a workaround to branch the approaches, so it's compatible with both versions.

@nicolas-grekas - I force-pushed a new update commit that supports both composer API versions. Composer::getVersion() returns the composer version number, and we simply branch the code depending on the version. I tested with current Composer snapshot and 1.10.5 and.

Thank you.

It seems to be ok.

I pushed some changes before merging.
