Extracting a package's source does not preserve workspace's resolver

[epage]

Bug Description

When pulling out a project's source to build it independent of its workspace, it should pull along the resolver field but isn't.

note: cargo originally didn't do this but was later updated to do this (rust-lang/cargo#10911, rust-lang/cargo#10961).

note that this will only affect things if the lockfile needs to be generated.

Your maturin version (maturin --version)

0.14.17

Your Python version (python -V)

Python 3.10.6

What bindings you're using

Does cargo build work?

• Yes, it works

If on windows, have you checked that you aren't accidentally using unix path (those with the forward slash /)?

• Yes

Steps to Reproduce

1. Download source
2. See no resolver set in typos-1.14.7/rust_src/typos-cli/Cargo.toml
3. See resolver is set in https://github.com/crate-ci/typos/blob/master/Cargo.toml#L6
