Integration tests not building locally

I tried to run the integration tests as described in https://github.com/googleapis/gapic-generator-python/blob/main/DEVELOPMENT.md, and I get local build failures. Do we need to update the instructions?

My output is this:

```
bazelisk test //tests/integration:all

[...]

```

Targeting the `NO STATUS` tests above individually (rather than specifying `:all`) also yields `FAILED TO BUILD`
