File Formats: Update HEIF export dialogue screenshot and options
This patch attempts to update the wording for the HEIF export dialogue section.
- A new screenshot of the dialogue is added.
- Replaces the paragraph "These options are self-explanatory." with all options described
@Wormnest Hi! I'm not very familiar with this format, so let me know if any information is incorrect or needs to be explained further.
