Remove token column from deploy_tokens table
### Problem In [this issue](https://gitlab.com/gitlab-org/gitlab-foss/issues/63502), the tokens stored in the `token` column of the `deploy_tokens` table were encrypted into the `token_encrypted` column. Now that this transition was made, the `token` column should be removed. ### Proposal As described in the [avoiding downtime in migrations](https://docs.gitlab.com/ee/development/database/avoiding_downtime_in_migrations.html) guide, this can be achieved by following the steps below: 1. [x] Make sure `token` column is ignored. (completed in !87458) 1. [x] Drop the `token` column. (completed in !88334) 1. [x] Remove the ignore rule. (completed in !91100)
