docs: fix broken checklist rendering in the MongoDB migration guide (#8113)

The docs renderer doesn't style GitHub task-list syntax; each - [ ]
rendered as an orphaned checkbox floating above its bullet. The items
already carry bold labels, so plain bullets read the same without the
broken checkboxes.

 Work through this list before you switch production traffic over:
 
-- [ ] **Same database.** Your Prisma Next config points at the **same** database and connection string as v6.
-- [ ] **Server version.** Your MongoDB server is on 8.0 or newer.
-- [ ] **Dry run first.** Rehearse the whole flow on a throwaway copy of your database (`contract emit`, `db update --dry-run`, `db update`, `db verify`) and make sure `db verify` passes before you touch production.
-- [ ] **Index parity.** The indexes on each collection (`db.collection.getIndexes()`) match your contract.
-- [ ] **Validators.** Your existing documents pass the strict validators Prisma Next adds to each collection (see *Good to know* in step 4).
-- [ ] **Addressing.** Every call site uses storage names like `db.orm.users`, not model names.
-- [ ] **Transactions.** Every v6 `$transaction` now has a driver-session equivalent.
-- [ ] **Raw calls.** Every `$runCommandRaw`, `findRaw`, and `aggregateRaw` has a pipeline-builder or `mongodb`-driver replacement.
-- [ ] **Read-only trial run.** Run Prisma Next read-only alongside your v6 app for a while and compare the results. This surfaces any differences while v6 is still handling all the writes.
-- [ ] **Cutover and rollback.** Switch writes over only once the trial run looks good, and keep the v6 branch deployable. Rolling back is just a code rollback since your data never moved.
