bundler-audit found new advisories

The nightly bundler-audit run failed: https://github.com/hackclub/attend/actions/runs/34016829808

Bump the flagged gem(s), or add a justified entry to config/bundler-audit.yml if the advisory doesn't apply.

Start with the linked nightly bundler-audit run to identify the flagged gem or advisory. Review the dependency files and config/bundler-audit.yml, then either bump the affected gem or document why the advisory does not apply. Done means the audit run passes and any exception is justified.
