Update Claudius to 1.2.1

[mdales]

Updates Claudius package to v1.2.0, which is a quality of life improvements release with improvements to logging and the debug screen within Claudius.

Hmm, the Claudius CI needs updating as it missed that the giflib dependancy is one version back. Will fix and update this.

Hmm, CI is failing on ubuntu due to issues before it gets as far as trying to install anything OCaml related:

	x-maintenance-intent: ["(latest)"]
	x-ci-accept-failures: ["debian-11"] # Debian-11 includes ibsdl2-dev.2.0.14 but 2.0.18 is needed to avoid SDL_RenderGeometry error

Since we've established the reason for the Debian 11 failure #28359 (comment) it could make sense to silence the repeated red flag that it raises 🤷

This is specific to ubuntu-24.10 I think as it is failing similarly there on other PRs too, e.g. on #28528.
Polite ping @mtelvers 🙂
