Refactor conda installation to use environment file

The previous conda installation commands in the 'conda-installs-for-m1.sh' file and '.github/workflows/test.yml' have been removed. Instead, the necessary dependencies are now defined in a new 'environment.yml' file. This simplification will enhance readability and maintainability of the code.
