V98: Add alternative_formats to storage dimensions.

Adds a `text[]` column to `phoenix_kit_storage_dimensions` so each
dimension can specify additional output formats (e.g., WebP, AVIF)
alongside the primary format. The variant generator creates one
extra file instance per alternative format per dimension.

All operations are idempotent.

# `down`

# `up`
