Description

Fixes release action problem: https://github.com/run-llama/llama_index/actions/runs/8574427576/job/23501224052
Now both needs 0.4.x of google-generativeai.

This will trigger the 0.1.5 release of llama-index-multi-modal-llms-gemini

@logan-markewich PTAL
llama-index-multi-modal-llms-gemini must be released as soon as possible

@nicoloboschi I believe we still need to update the version number of this package as well in the pyproject.toml

[nicoloboschi]

IIUC the release action is performed if there is a change in the pyproject file. The current version never reached pypi so I believe that just merging this pr should be fine.

ah yes, you're right it didn't reach pypi. Okay let's give it a whirl. If it doesn't go thru our github actions I can publish/build manually for us.
