BI-1680 - Added Migration That Removes "Somoclone" Breeding Method

[mlm483]

COPIED FROM #344

Description

Story: BI-1680

Per the Desired Behavior section of the Jira story, I added a migration to remove the "Somoclone" breeding method from the system preset breeding methods.

This bi-web PR takes care of updating the import template.

Dependencies

bi-web branch: feature/BI-1680.

Testing

1. Checkout this branch, git checkout feature/BI-1680.
2. Run bi-api.
3. Ensure that the new migration ran (V1.20.0 V1.21.0) by checking the bidb database, SELECT * FROM flyway_schema_history;.
4. Ensure that the "Somoclone" breeding method is not listed in the DeltaBreed UI, under Program Administration > Breeding Methods.
