Upgrade ingestor API dependencies

[hrodmn]

The ingestor API is stuck on some very old versions of important dependencies like stac-pydantic which might cause some issues for users who try loading STAC v1.1.0 (e.g. stac-utils/stac-pydantic#166):

eoapi-cdk/lib/ingestor-api/runtime/requirements.txt

Lines 1 to 11 in 63279d5

	Authlib==1.0.1
	cachetools==5.3.0
	fastapi>=0.75.1
	orjson>=3.6.8
	psycopg[binary,pool]>=3.0.15
	pydantic_ssm_settings>=0.2.0
	pydantic>=1.9.0
	pypgstac==0.8.5
	requests>=2.27.1
	# Waiting for https://github.com/stac-utils/stac-pydantic/pull/116
	stac-pydantic @ git+https://github.com/alukach/stac-pydantic.git@patch-1

The key might be to upgrade pydantic-ssm-settings 😅 because that has a firm requirement for pydantic<2.

• Update pydantic-ssm-settings for pydantic>=2
• Switch from fork of stac-pydantic to latest version (3+)
• Upgrade other outdated dependencies (like FastAPI)

It might be worth bringing in the updates from the VEDA deployment: https://github.com/NASA-IMPACT/veda-backend/tree/develop/ingest_api
