Change work_histories migration to insert via SQL

[CatalinVoineag]

Context

The data migration BackfillApplicationChoicesWithWorkExperiences was inserting records via
ActiveRecord. This caused an incident, known as The Big Touch. Many application choices, forms, and candidates had their updated_at updated and this caused some of our APIs to be slow.

We still need to run this migration in sandbox so we thought it's a good idea to change this migration to insert records via SQL avoiding any callbacks.

This doesn't need to run again in production, only sandbox, which has around 38k records that need updating

Ran this locally with 120k records, the workers finished their 5k batch insert in around 20 seconds, much faster than before when we were using ActiveRecord.

Guidance to review

Things to check

• If the code removes any existing feature flags, a data migration has also been added to delete the entry from the database
• This code does not rely on migrations in the same Pull Request
• If this code includes a migration adding or changing columns, it also backfills existing records for consistency
• If this code adds a column to the DB, decide whether it needs to be in analytics yml file or analytics blocklist
• API release notes have been updated if necessary
• If it adds a significant user-facing change, is it documented in the CHANGELOG?
• Required environment variables have been updated added to the Azure KeyVault
• Inform data insights team due to database changes
• Make sure all information from the Trello card is in here
• Rebased main
• Cleaned commit history
• Tested by running locally
• Add PR link to Trello card
