Require Multipass>=1.14.1 for launching Ubuntu 24.04 (Noble).

Previously, Multipass had been using the snapcraft:devel alias for 24.04 images (#602). This worked until last month when the devel alias started pointing to 24.10 images.

Once Multipass 1.14.1 is released to latest/stable and to homebrew, this can be reverted and the minimum Multipass version will be bumped to 1.14.1 (#638).

Fixes #628 (CRAFT-3270)
