RHIDP-14083: fix: set EXTERNAL_PROVIDERS_DIR in image for unified config

[Jdubrick]

Description

• The default_run.yaml defaults the external providers directory to ~/.llama/providers.d if this environment variable is unset. As part of the image build however the lightspeed-providers external providers are added to /app-root/providers.d. Adding this environment variable ensures that unified config users get the correct path set.
