Add --alter option to insert command

[simonw]

To tell Datasette to alter tables to add any missing columns. Requires 1.0a9 or higher: https://docs.datasette.io/en/latest/changelog.html#a9-2024-02-16

Without alter-table:

echo '{"foo": "bar", "baz": 1}' | dclient insert staff test_alter --create - --json --alter

Error: Permission denied: need alter-table

Then with a new token with that permission enabled... it worked!
