Removal of `Cargo.lock` from `rust-src` causes Bevy CI to fail

[BD103]

Description

• Bevy issue: build-wasm-atomics CI check failing bevyengine/bevy#14662
• Regression PR: Remove the root Cargo.lock from the rust-src component #128685
• Original CI job: ci.yml

As part of Bevy's CI, we check that it builds with wasm32-unknown-unknown with target-feature=+atomics,+bulk-memory on nightly. This check has recently started failing due to #128685. I found this after running cargo-bisect-rustc, whose output can be found below:

Wonderful! I'll close this and test it tomorrow!
