Remove unnecessary length check for repo's Description & Website (#21194)
Remove unnecessary length check for repo's Description & Website (#21194)

Follows #21119

The manual length check doesn't make sense nowadays:
1. The length check is already done by form's `binding:MaxSize` (then the manual check is unnecessary)
2. The CreateRepository doesn't have such check (then the manual check is inconsistent)

So this PR removes these manual length checks.
