chore: migrate non-mathlib part of 100.yaml and 1000.yaml

[joneugster]

Removes all entries from 100.yaml and 1000.yaml which do not have mathlib declarations. These entries are moved to yaml files on the website. The website merges its yaml files containing external links with the yaml files from mathlib.
