fix: use --overrides (not --override) in AzDO publish pipeline template (#75)

The Azure DevOps publish pipeline template was using `--override` (singular)
which is not a recognized option in `apiops publish`. The correct flag is
`--overrides` (plural). This caused the pipeline to fail with an unknown-option
error regardless of which COMMIT_ID_CHOICE was selected.

The incremental step already correctly passed `--commit-id $(Build.SourceVersion)`
when `publish-artifacts-in-last-commit` is chosen (via the `ne()` condition).
This fix ensures the command is actually valid so the commit-id flag is honoured.
