Fold package managers lock files #3523

Almost a duplicate of https://github.com/sindresorhus/refined-github/pull/1085

Perhaps collapsing a limited number of hardcoded lockfiles would be useful and relatively easy to implement though

I remember we had an identical issue to this and we resolved it with:

GitHub’s existing solution is good enough:

• files are already collapsed
• they still take a little bit of visual space not to miss them completely.

If you want to have them take even less space, this is doable with CSS
