[PATCH] init/Kconfig: extend -Wno-array-bounds to gcc 13

[Tom Rix <trix@redhat.com>]

With gcc 13.0.1 on x86, there are several false positives like

drivers/net/ethernet/microchip/sparx5/sparx5_psfp.c:167:31:
  error: array subscript 4 is above array bounds of ‘const struct sparx5_psfp_gce[4]’ [-Werror=array-bounds=]
  167 |                 gce = &sg->gce[i];
      |                        ~~~~~~~^~~
In file included from drivers/net/ethernet/microchip/sparx5/sparx5_psfp.c:8:
drivers/net/ethernet/microchip/sparx5/sparx5_main.h:506:32: note: while referencing ‘gce’
  506 |         struct sparx5_psfp_gce gce[SPX5_PSFP_GCE_CNT];
      |                                ^~~

The code lines for the reported problem
	/* For each scheduling entry */
	for (i = 0; i < sg->num_entries; i++) {
		gce = &sg->gce[i];

i is bounded by num_entries, which is set in sparx5_tc_flower.c
	if (act->gate.num_entries >= SPX5_PSFP_GCE_CNT) {
		NL_SET_ERR_MSG_MOD(extack, "Invalid number of gate entries");
		return -EINVAL;
	}
..
	sg->num_entries = act->gate.num_entries;

So disable array-bounds as was done on gcc 11 and 12
