Pull migrations from spar repo

[franTarkenton]

The docker compose that creates the spar postgres database, only has a single migration that comes from the common/database init scripts from that repo.

The docker compose should instead have a step that retrieves all the migrations from the spar folder: https://github.com/bcgov/nr-spar/tree/main/backend/src/main/resources/db/migration, and then the migration step will run those migrations.
