This pull request automates the release of version 2.59.1 for the project.

Code Review

This pull request is an automated release for version 2.59.1. The changes primarily consist of version bumps in various configuration files, which is standard for a release. I've found one significant inconsistency in the versioning of the gax-httpjson artifact that should be addressed.

[gemini-code-assist]

There appears to be a version inconsistency for gax-httpjson. This file specifies version 0.152.1, but other files like gax-java/gax-httpjson/pom.xml are being updated to version 2.67.1 (inherited from gax). This is likely due to a misconfiguration in release-please where pom.xml files are updated using gax's version ({x-version-update:gax:current}), but versions.txt has a separate versioning scheme for gax-httpjson.

To resolve this, gax-httpjson should be consistently versioned. Given that POMs are being updated to 2.67.1, this file should reflect that as well.

gax-httpjson:2.67.1:2.67.1
