Can't cargo publish --workspace --dry-run if the versions already exist

[epage]

Problem

In testing #1169 on cargo release now that #14721 is fixed, I came across another way you can't dry-run existing versions: the overlay registry blocks it

error: failed to prepare local package for uploading

Caused by:
  failed to get `clap_builder` as a dependency of package `clap v4.5.20 (/home/epage/src/personal/clap)`

Caused by:
  found a package in the remote registry and the local overlay: clap_builder@4.5.20

Steps

$ cargo install cargo-release
$ git clone git@github.com:clap-rs/clap.git
$ cd clap
$ cargo +nightly publish -Zpackage-workspace --package clap_
lex --package clap_builder --package clap_derive --package clap --package clap_complete --package clap_complete_fig --
package clap_complete_nushell --package clap_mangen --dry-run --allow-dirty

Possible Solution(s)

Remove the restriction on the overlay which comes at the risk of it being abused.

In addition to being accepted, wanted to record some notes from the team's discussion

• We considered making this a lint or flag but those aren't generally dynamic which this would need. Granted, --ignore-rust-version is kind of like that.
• While we want to be cautious about what behavior we allow for this Source, this is still all internal, so it should be good.
• The current error is more strict than the single-package case, so removing the error brings them inline with each other
• The important thing is that we warn which we should already get from fix(publish): Downgrade version-exists error to warning on dry-run  #14742
