Description

Resolves #9058 and #7456 (again)

When I tested my previous PR (#10175) on another repo, I discovered an issue with a missing dep in the pruned lockfile

To reproduce this in the with-yarn example repo:
cd apps/web && bun install dd-trace
and
cd apps/docs && bun install @opentelemtry/api

Then run prune for web and try bun install --frozen-lockfile and you'll get this:

error: Failed to resolve peer dependency '@opentelemetry/api' for package '@opentelemetry/core'
    at bun.lock:1:16974
InvalidPackageInfo: failed to parse lockfile: 'bun.lock'

Issue 1 -- Deserialization casing

The underlying error is rather straightforward -- it was deserializing most dependencies (peerDependencies, devDependencies, optionalDependencies) to other 😄

This is because it just needed #[serde(rename_all = "camelCase")] since the rust names are snake case. This is why dependencies happened to work -- it's the same in snake and camel case.

By virtue of being in other, all non-dependencies packages were effectively ignored during the pruning process, and don't always end up in the resulting lockfile.

Issue 2 -- optionalPeers

After fixing that, I also stumbled upon another issue:

WARNING  Unable to calculate transitive closures: No lockfile entry found for 'next/@playwright/test'

This is because we weren't accounting for the optionalPeers property. next doesn't actually require you have @playwright/test, it's an optional peer. I fixed this as well.
