aws[patch]: Remove numpy dependency (previously patch to support numpy2)

[ghinch]

Increasing version of numpy to include 2.x.x for the langchain-aws package. Fixes #147

Thanks for submitting this change. langchain-community and langchain are both still using < 2 for numpy. https://github.com/langchain-ai/langchain/blob/master/libs/community/pyproject.toml#L51
https://github.com/langchain-ai/langchain/blob/master/libs/langchain/pyproject.toml#L49

Are there any implications of allowing v2? What would be the default numpy version installed with this change?

Thanks for following up @3coins

This PR follows on from the update to langchain-corewhich was released as part of 0.3.19 . I've followed the pattern there which was to simply set the version of numpy to "less than 3". So the support would be there for any 2.x.x version. I believe the default behavior in langchain-core is for it to install the lowest supported version (1.26.2 for core).

I have also opened similar PRs for langchain langchain-ai/langchain#28183 and langchain-community langchain-ai/langchain#28184.

I am not aware of any changes in the 2.x.x versions of numpy which are breaking for any of the Langchain modules (and the CI seems to be passing for all PRs I opened), but I'm happy if you would like to wait for the above PRs to be merged first.

Since, numpy is already present as dependency in langchain packages, we can remove it as a direct dependency in langchain-aws; I don't think it is directly used anywhere within this package. Run poetry lock to update the poetry lock file, after you remove it in pyproject.toml. I have tested this change, and I don't see any failures. Thanks again for raising this PR.

Thanks @3coins, makes sense.
I've run poetry remove numpy and committed this change

LGTM!
