Build(deps-dev): bump curb from 1.3.1 to 1.3.2

[dependabot]

Bumps curb from 1.3.1 to 1.3.2.

Changelog

Sourced from curb's changelog.

1.3.2

• Fix Curl::PostField GC marking so block-backed content fields remain valid across GC and compaction.
• Fix upload read/seek callbacks to preserve Ruby exceptions, avoid unsafe unwinds through libcurl, and reject reads larger than libcurl's supplied buffer.
• Fix multipart POST/PATCH/PUT cleanup so partially built native forms are freed when form construction raises.
• Restore Curl::Easy#last_error after Easy#close by reattaching the libcurl error buffer to the reinitialized handle.
• Fix Curl::Easy#clone with put_data so upload callbacks and upload state belong to the clone instead of the original handle.
• Add regression coverage for native callback, multipart cleanup, clone upload, close/error-buffer, and PostField GC safety.
