New viz_schism_fim image with conda managed environment.

[groutr]

This PR accomplishes several things

1. Updated base image to amazonlinux 2023
2. Environment managed by conda

Managing the execution environment with conda comes with several advantages:

1. Easier dependency management
2. Conda's guarantees on a consistent environment
3. Reproducible environments (via the lockfile) Conda-lock is used to solve the environment and render a platform-specific lock file.
