Update monorepo dependencies

[caendesilva]

I think these needs to be merged together:

• Supersedes https://github.com/hydephp/develop/pull/1902
• Supersedes https://github.com/hydephp/develop/pull/1906
• Supersedes https://github.com/hydephp/develop/pull/1925

Additionally it removes some packages from the monorepo that we haven't used in a long time, and are generally better to install through an isolated setup like a dedicated Composer root or using a Phar:

• Remove Rector from the monorepo toolset
• Remove PHP Parallel Lint from the monorepo toolset
• Remove PHP CodeSniffer from the monorepo toolset

Not sure why we lost so much type coverage...

Too many incompatibilities, so gave up with the new Psalm version and reverted to the original.
