Replace via.placeholder.com images with picsum.photos images

[viemmsakh]

via.placeholder.com was purchased by a warehouse company and as a result all image URLs in data.json are invalid. This PR replaced the image URLs in data.json with valid image URLs from picsum.photos.

Additional Details:

Image IDs on picsum.photos are not sequential and therefore the image IDs used are not sequential. A script was wrote to parse the v2/list endpoint provided by picsum so that only valid IDs were used in this PR.

There are only about 995 unique image IDs on picsum; so there are only 995 unique image URLs in this PR change. Since there are 5000 images in the data.json I decided to loop though the 995 unique IDs while replacing the image URLs. As a result some picsum images are repeated. For example, the first image with id 0 shows up 6 times.

I opened an issue on the picsum source repo asking for permission to use their service in this project.

Permission was granted along with a suggestion for using the seed generated images instead of hard coding image IDs. PR updated to use the recommended seed generation instead of hard coded IDs.

Been a while since this was put up and mentioned. I cam across this issue because a few doc site use these apis for example https://tanstack.com/router/v1/docs/framework/react/examples/location-masking which is now broken
