Janitorial: update more dependencies (#40297)

* packages/changelogger: bump dependencies

symfony/process: PHP >=5.5.9 → >=7.2.5 (earlier releases have security bulletins for Windows)
symfony/console: PHP >=5.5.9 → >=7.2.5 (to match the above)
PHP: 7.2 → 7.2.5 (so we can have the above versions)

* jetpack-autoloader and jetpack-composer-plugin: bump dependencies

composer/composer: 2.3 and up require PHP 7.2.5, so we're stuck with LTS for now
composer-plugin-api: same as above

* wpcomsh: remove unneeded dependencies

* Add changelogs

* Update lockfiles

* Update projects/packages/autoloader/changelog/fix-bump_composer_versions_round2
