Add prettier for non-python formatting

Adding prettier for consistent formatting of non-python files. Ruff format only applies to python files, however, other files in the repo still have similar concerns (consistency, whitespace thrashing, etc). Prettier addresses this concern in the same way as ruff; minimal configurability to prevent bikeshedding. All non-conformant files have been formatted to pass the pre-commit hook. Very few changes were needed; several yaml files were modified to have consistent whitespace and indentation, including the pre-commit configuration file. Modern text editors and IDEs (efficiently) support prettier via plugin; this is recommended for local formatting. A cli tool is available, however, prettier itself is written in javascript so it is only accessible via npm/yarn (`npx prettier`/`yarn dlx prettier`). While this is unfortunate, there are very few tools that format general source files, and none within the python ecosystem. Pre-commit does address this capability gap indirectly. It can be run via `pre-commit run prettier`, either with the `--all-files` flag or by adding a modified file to your working tree. While suboptimal, this does allow local formatting/validation if needed.
