Lint rules prevent:
* Invalid naming conventions for new migrations
* Loop constructs in migrations - these should be used with caution
and are therefore a warning rule, use `// eslint-disable-next-line
no-restricted-syntax` to prevent this rule from firing where a loop is
required
* Returing within a loop - this is usually meant to be a
continue/break
* Multiple joins - these can be badly performing migrations, so should
be treated with caution, disable the rule for the line if the risk is
understood / the migration cannot be written without it

We use Offer names for the Stripe Coupon name - which has a limit of 40
characters. We are now introducing a limit of 40 characters to Offer
names too. This migration ensures that all our data in the DB is valid.
