Build(deps-dev): bump curb from 1.3.6 to 1.3.7

[dependabot]

Bumps curb from 1.3.6 to 1.3.7.

Changelog

Sourced from curb's changelog.

1.3.7

• Pin Curl::Easy wrappers during GC compaction so libcurl completion dispatch cannot follow a stale Ruby object reference (#482).
• Fix FTP option configuration (#481): add Curl::Easy#ftp_create_missing_dirs and its setter, export the available CURLFTP_CREATE_DIR_* mode constants, and route detected scalar/string FTP options through Curl::Easy#set.
• Make Curl::Multi#perform and scheduler-driven Curl::Easy#perform nonblocking under Fiber schedulers while preserving cancellation and final-yield behavior, including schedulers without io_select.
