Aileen Nowak eef7932e94 Refactor: fetch image dimensions from local file storage (#8900)
refs #8868

- Removed image-size in blog logo fn for meta data and made it synchronous
- Renamed `image-size-from-url.js` to `image-size.js` (incl. the test)
- Added second fn `getImageSizeFromFilePath` that reads from local file storage
- Added guard in `getImageSizeFromUrl` that checks if the image should be on local file storage and uses the new fn then instead
- Added a fn `fetchDimensionsFromBuffer` that takes the file buffer and returns an `imageObject` with dimensions.
- Added a new utils.js in `adapters/storage` for getting the file storage path
