Two pages imported PySchemaAddSetup under the alias SchemaAddSetup, and
Mint resolved only the first, failing `mint validate` on
management/table.mdx. Both pages now import it unaliased.
TsAddProgress was added to the generated tables snippets by hand in
lancedb/docs#243 and dropped by the next regeneration, leaving
ingestion/insert.mdx with a missing import. Its example is restored
unchanged as a test in docs/web-tests/ts/tables.test.ts, which checks
that the callback reports the finished write.
