Support workspace.members parsing for Cargo.toml analysis

Description

Hi 👋 !
Thanks for such awesome project!
I'll try to add workflow with trivy as vulnerability scanner for our Rust project, but I faced some problems.
Cargo.toml of our project looks like this:

[workspace.package]
version = "2.8.1"

[workspace]
members = ["casr", "libcasr"]

It doesn't have any dependencies in workspace, all dependencies are located in members. It seems to me, that it is possible to parse members section and then parse appropriate Cargo.toml configs to extract dependencies.
I have already tried, it works for me. I can open PR:).

It makes sense. I've created #5283.
