Add missing header in AllocatorConfig.h [14.0.x]

[fwyzard]

PR description:

The header checks are failing with

src/HeterogeneousCore/AlpakaInterface/interface/AllocatorConfig.h:42:5: error: 'uint8_t' does not name a type
   42 |     uint8_t fillAllocationValue = 0xA5;
      |     ^~~~~~~
src/HeterogeneousCore/AlpakaInterface/interface/AllocatorConfig.h:6:1: note: 'uint8_t' is defined in header '<cstdint>'; did you forget to '#include <cstdint>'?

This PR adds the missing include header file.

PR validation:

Header checks should now pass.

I'm not going to call this urgent, because the release builds fine.
However, in case we care about fixing the header check warnings in the 14.0.x IBs, please merge this at your convenience.
