Methods from Identifiers\Random were currently implemented using
the Mersenne Twister general-purpose pseudorandom number generator.
As randomness is often used as a source to generate credentials,
and to also offer unbiaised results for games, this changes switch
to the CSPRNG method random_int. The random_bytes method was already used.
According PHP manual, the "cryptographically secure pseudo-random number
generator (CSPRNG) API provides an easy and reliable way to generate
crypto-strong random integers and bytes for use within cryptographic contexts."
As our library is PHP 7+ (actually PHP 8.1+), the CSPRNG methods are always
available.
