Update Gifu to 3.3.1

[kean]

Fixes #21160

Fortunately, I fixed this crash in Gifu two years ago 😃

The latest version is 3.4.0, but it is not on CocoaPods.

To test:

The crash is a race condition and you have to be very unlucky to reproduce it.

Regression Notes

1. Potential unintended areas of impact: GIF rendering
2. What I did to test those areas of impact (or what existing automated tests I relied on): tested manually
3. What automated tests I added (or what prevented me from doing so): n/a

PR submission checklist:

• I have completed the Regression Notes.
• I have considered adding unit tests for my changes.
• I have considered adding accessibility improvements for my changes.
• I have considered if this change warrants user-facing release notes and have added them to RELEASE-NOTES.txt if necessary.
