[Issue #191] Cleanup makefile commands around OpenSearch (#192)

## Summary
Fixes #191

### Time to review: __5 mins__

## Changes proposed
Adjusted a few makefile commands / added some additional docs

Renamed `db-recreate` to `volume-recreate` as the command also recreates
the OpenSearch volume.

Added a command for populating your OpenSearch index locally for
opportunities rather than needing to build the full command yourself.

## Context for reviewers
As we've added more commands to the Makefile, we haven't kept ontop of
how they all interact. This should add some level of clarity to the
commands.

The new `make populate-search-opportunities` command is a much easier
way of writing out the full command of `docker compose run --rm
grants-api poetry run flask load-search-data load-opportunity-data`.

## Additional information
Note that we have a `make help` command which prints out any command
with a `## help text` on the target definition in the makefile:
