Add ability to enable pgstac.update_collection_extent in database bootstrapper

[hrodmn]

It would be nice to be able to enable pgstac's "update collection extent using items" feature here:

eoapi-cdk/lib/database/bootstrapper_runtime/handler.py

Lines 146 to 167 in 70e8437

	def customization(cursor, params) -> None:
	"""
	CUSTOMIZED YOUR PGSTAC DATABASE
	ref: https://github.com/stac-utils/pgstac/blob/main/docs/src/pgstac.md
	"""
	if str(params.get("context", "FALSE")).upper() == "TRUE":
	# Add CONTEXT=ON
	pgstac_settings = """
	INSERT INTO pgstac_settings (name, value)
	VALUES ('context', 'on')
	ON CONFLICT ON CONSTRAINT pgstac_settings_pkey DO UPDATE SET value = excluded.value;"""
	cursor.execute(sql.SQL(pgstac_settings))
	if str(params.get("mosaic_index", "TRUE")).upper() == "TRUE":
	# Create index of searches with `mosaic`` type
	cursor.execute(
	sql.SQL(
	"CREATE INDEX IF NOT EXISTS searches_mosaic ON searches ((true)) WHERE metadata->>'type'='mosaic';"
	)
