Update OpenSearch endpoint ENV variable

Why these changes are being introduced:
The ENV variable name for the OpenSearch endpoint has been changed in
Terraform to match the name formatting for other TIMDEX ENV variables,
so the code here needs to change as well.

How this addresses that need:
* Update ENV variable name from OPENSEARCH_ENDPOINT to
  TIMDEX_OPENSEARCH_ENDPOINT across the repo, including in the README.

 - `AWS_REGION` = Only needed if AWS region changes from the default of us-east-1.
-- `OPENSEARCH_ENDPOINT` = If using a local Docker OpenSearch instance, this isn't needed. Otherwise set to OpenSearch instance endpoint _without_ the http scheme, e.g. `search-timdex-env-1234567890.us-east-1.es.amazonaws.com`. Can also be passed directly to the CLI via the `--url` option.
 - `OPENSEARCH_REQUEST_TIMEOUT` = Only used for OpenSearch requests that tend to take longer than the default timeout of 10 seconds, such as bulk or index refresh requests. Defaults to 30 seconds if not set.
 - `SENTRY_DSN` = If set to a valid Sentry DSN, enables Sentry exception monitoring. This is not needed for local development.
 - `STATUS_UPDATE_INTERVAL` = The ingest process logs the # of records indexed every nth record (1000 by default). Set this env variable to any integer to change the frequency of logging status updates. Can be useful for development/debugging.
