[dudoslav]

Add azure-identity-cpp into dependencies

I confirmed locally that this is working:

bash run-local-tiledb.sh

cat tiledb-feedstock/recipe/tiledb-patches/system-ports/azure-identity-cpp/*
## set(VCPKG_POLICY_EMPTY_PACKAGE enabled)
## { "name": "azure-identity-cpp", "version-string": "system" }

conda build tiledb-feedstock/
##
##     azure-identity-cpp:            1.6.0-hf1915f5_1            conda-forge
