Remove redundant paragonie/random_compat dependency

[brendt]

This package depends on paragonie/random_compat: ^2.0, but also php: ^7.3||^8.0. Since random_bytes and random_int were added in PHP 7.0, the dependency on paragonie/random_compat seems redundant?

Thanks for the PR and including us in your scan!

Does it make sense to submit pull requests to this repository? Won't it be overwritten by the next run of the core splitter?

[KorvinSzanto]

@mlocati you are absolutely correct, a few things are happening here that make this confusing:

1. @brendt ran a automated scan of projects in packagist to see which had redundant polyfill dependencies and graciously opened pull requests to fix the redundant ones he found.
2. We use mediawiki's composer merge plugin, so Brent's scan only sees the top level dependencies for concretecms/concretecms and sees the actual list of dependencies here in this split repo
3. I accidentally merged this here before realizing it was against the split

All that said, I've resolved this by git aming this patch in the proper repository and the accidental merge has already been wiped away by the next core split.
