Add lorempixel, lorempicsum and unsplash entity

[deerawan]

Based on the latest version of @faker-js/faker, they are treated as entity not part of Image entity anymore

Hello 👋
Just want to make you aware that the image feature is now 100% non functional as placeimg is no longer working. Faker has already released an update for this, it could be as easy as releasing bumping up the version? no idea 🤷 , just an FYI and aa thank you for the extension :)

I'm not the maintainer but I just opened a PR #76 which should fix the placeimg issue.
You can checkout the commit, and install it as a local extension:

vsce package
code --install-extension vscode-faker-2.0.1.vsix

@deerawan and @TastefulElk Is the repo dead? I could help maintain it, if you want my help.
