chore(db-*): import migration args as type

[sondreorland]

What?

If you have verbatimModuleSyntax enabled in tsconfig then creating migrations will give a TypeScript error due to the args not being imported as types.

When a migration is created we get this:

import { MigrateDownArgs, MigrateUpArgs } from '@payloadcms/db-mongodb'

Why?

This causes:

'MigrateDownArgs' is a type and must be imported using a type-only import when 'verbatimModuleSyntax' is enabled.
'MigrateUpArgs' is a type and must be imported using a type-only import when 'verbatimModuleSyntax' is enabled.

Screenshot:

How?

Added type in front of the imported types to avoid the error, which also makes it clearer that this is a type import.

import type { MigrateDownArgs, MigrateUpArgs } from '@payloadcms/db-mongodb'
