Stop using datasette.table_metadata()

Lines 662 to 675 in ded886e

	def introspect_tables(conn, datasette, db_name):
	db = sqlite_utils.Database(conn)
	table_names = db.table_names()
	view_names = db.view_names()
	table_metadata = {}
	table_namer = Namer("t")
	for table in table_names + view_names:
	datasette_table_metadata = datasette.table_metadata(
	table=table, database=db_name
	)
	columns = db[table].columns_dict

This was not a documented method and I'm planning to remove it in Datasette 1.0:

• Table configuration settings should work in both metadata.yml and datasette.yml datasette#2247

After I release 1.0a8 I'm going to update the tests here to test against both 0.x and 1.x - https://github.com/simonw/datasette-graphql/blob/main/.github/workflows/test.yml - as I did with datasette-cluster-map in simonw/datasette-cluster-map@d2c3a2b
