Warning when compiling master

[daggy1234]

So I use rust-analyzer with ST4, and build rust-analyzer from master. When performing the routine pull and install, I got a wraning. Works fine but just thought I would report

$ cargo xtask install --server
    Finished dev [unoptimized] target(s) in 0.11s
     Running `target\debug\xtask.exe install --server`
$ cargo install --path crates/rust-analyzer --locked --force --features force-always-assert
  Installing rust-analyzer v0.0.0 (C:\Users\<name>\rust-analyzer\crates\rust-analyzer)
    Updating crates.io index

    Finished release [optimized] target(s) in 0.74s

    Replaced package `rust-analyzer v0.0.0 (C:\Users\<name>\rust-analyzer\crates\rust-analyzer)` with `rust-analyzer v0.0.0 (C:\Users\<name>l\rust-analyzer\crates\rust-analyzer)` (executable `rust-analyzer.exe`)

The warning is:
warning: package crossbeam-epoch v0.9.4 in Cargo.lock is yanked in registry crates.io, consider running without --locked

Anyway thanks!

crossbeam-epoch 0.9.5 fixed a case of UB: crossbeam-rs/crossbeam#694 Older versions in the 0.9.x branch were probably yanked for this reason.
