pulsar-client dependency version change

[dturaev]

Description of the bug:

Hi, the installation of dependencies via poetry install for https://github.com/google/generative-ai-docs/examples/gemini/python/docs-agent/ according to the tutorial https://ai.google.dev/gemini-api/tutorials/docs-agent currently doesn't work:

  - Installing pulsar-client (3.6.0): Failed

    | Unable to find installation candidates for pulsar-client (3.6.0)
    |
    | This is likely not a Poetry issue.
    |
    |   - 0 candidate(s) were identified for the package
    |
    | Solutions:
    | Make sure the lockfile is up-to-date. You can try one of the following;
    |
    |     1. Regenerate lockfile: poetry lock --no-cache --regenerate
    |     2. Update package     : poetry update --no-cache pulsar-client
    |
    | If neither works, please first check to verify that the pulsar-client has published wheels available from your configured source that are compatible with your environment- ie. operating system, architecture (x86_64, arm64 etc.), python interpreter.

It seems that only pulsar-client 3.6.1 is available from PyPI (https://pypi.org/project/pulsar-client/#history). Thanks!

Actual vs expected behavior:

Expected: poetry install installs project dependencies. Actual: Installation fails due to missing package version.

Any other information you'd like to share?

I tried adding pulsar-client = "^3.6.1" to pyproject.toml and regenerating the lock file via poetry lock, but this takes forever on my machine, so not a viable solution.
