fix: bump ZAI_CONFIG_ENTRIES_COUNT_MAX to 400

[MilanGarnier]

Why

Master has been unable to publish a dev build since #3997 merged. That PR
added the DD_TRACE_PROPAGATION_BEHAVIOR_EXTRACT config plus new
per-integration entries, pushing the total number of registered config
entries to ~302 - over the compile-time cap of 300 in
ZAI_CONFIG_ENTRIES_COUNT_MAX.

This trips the static assert in ext/configuration.c:

#define NUMBER_OF_CONFIGURATIONS sizeof((uint8_t[]){DD_ALL_CONFIGURATIONS})
_Static_assert(NUMBER_OF_CONFIGURATIONS < ZAI_CONFIG_ENTRIES_COUNT_MAX,
               "There are more config entries than ZAI_CONFIG_ENTRIES_COUNT_MAX.");

which breaks the compile tracing extension jobs

Fix

Bump ZAI_CONFIG_ENTRIES_COUNT_MAX from 300 to 400 to restore extra
capacity above the current count (~302) for new config entries.
