Version 1.5.0 should be yanked

[carloskiki]

Describe the bug at a high level.

criterion depends on regex = "1.5". If you have a dependency on criterion, or any crate that depends on regex = "1.5", building with -Zminimal-versions fails because regex does not build on version 1.5.0 (with some feature flag enabled). Therefore, this version should be yanked in order to make builds depending on regex = "1.5" succeed.

See CHANGELOG.md version 1.5.1.

What are the steps to reproduce the behavior?

With any crate having regex = "1.5":
1.

cargo +nightly update -Zminimal-versions

cargo build

I think the resolution here is to increase the minimal version. I don't like to yank unless there's a very compelling reason to do so.
