Update beberlei/assert for PHP 8 compatibility

Run `composer update beberlei/assert` using composer 2.3.8 on PHP 8.1.7

Updating other packages without updating this fails with:

```
Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - beberlei/assert v3.2.2 requires php ^7 -> your php version (8.1.7) does not satisfy that requirement.
    - spomky-labs/otphp v10.0.1 requires beberlei/assert ^3.0 -> satisfiable by beberlei/assert[v3.2.2].
    - spomky-labs/otphp is locked to version v10.0.1 and an update of this package was not requested.
```
