Workspace does not automatically reload when a package is added to a workspace crate

rust-analyzer version: rust-analyzer version: 0.3.1860-standalone (5346002 2024-02-25)

rustc version: rustc 1.78.0-nightly (6672c16af 2024-02-17)

relevant settings:

• A cargo workspace with a root Cargo.toml file with only a workspace table and no direct code units.
• A workspace setting with a glob; e.g.,

[workspace]
members = ["crates/*"]
resolver = "2"

• A blank crate in crates directory (cargo new --vcs none --bin crates/test-bin)

steps to reproduce:

• Open VS Code with a workspace project structure and glob members as described above.
• Add a new package to a crate (cargo new -p test-bin clap)
• Observe RA does not reload
• Observe RA does not provide typeahead hints for clap.
• Manually trigger "Reload Workspace"
• Observe RA provides typeahead hints for clap.

The bug report for #16550 made me realize #10442 is likely related. RA should always check for Cargo.tomls represented by the workspace members regardless of how deep they are in the tree.
