Refactor colorspace handling in CollectColorspace plugin

- Refactored the code to use more descriptive variable names
- Added a helper method `_colorspace_name_by_type` to retrieve the colorspace name based on its type
- Updated logging statements for better clarity and readability

Fix validation error in ValidateColorspace plugin

- Added a check to ensure that the OCIO config contains at least one colorspace
- If no colorspaces are found, an error is raised with appropriate messages and descriptions
- Updated logging statement to include a pretty-printed representation of the config's colorspaces
