Normalize schema_sqlite.rb to reflect TableDefinitionColumnLimits initializer (#2569)

The table_definition_column_limits initializer (PR #1669) applies a
default limit of 255 to all string columns during schema:load, but
schema_sqlite.rb was never re-dumped after it landed. This caused
drift on every subsequent migration PR that dumped the schema.

Re-dump from schema:load → schema:dump to make the file idempotent.
