[web-php][PR #413] - Update checksums for 8.0.8 to match published archives

You can view the Pull Request on github: https://github.com/php/web-php/pull/413 Opened By: tianon Pull Request Description: See https://github.com/php/web-php/commit/64de340efe5d43092a182d9366db3af2ff1ed917#r52925273 :sweat_smile: I calculated these by wget -qO- 'https://www.php.net/distributions/php-8.0.8.tar.xz' | sha256sum (and .bz2 and .gz). Alternatively, perhaps the published archives should be updated to the versions that matched these checksums? (Not sure which fix is correct, but figured I'd get a PR up in case updating the checksums is the right answer.)
