[nrf fromlist] snippets: wifi-enterprise: Resize data heap to fix RAM overflow

Inclusion of CONFIG_WIFI_SHELL_RUNTIME_CERTIFICATES causes build time
RAM overflow issues. Decrease NRF_WIFI_DATA_HEAP_SIZE to accommodate
the RUNTIME_CERTIFICATES feature. Disable HEAP_MEM_POOL_IGNORE_MIN to let
the system calculate the required K_HEAP size.
Fixes SHEL-3600.

Upstream PR #:88861.
