[Bug?]: Specifying supportedArchitectures..current is incompatible with --immutable-cache

Self-service

• I'd be willing to implement a fix

Describe the bug

When yarn install --immutable --immutable-cache is run on a project (e.g. in a CI environment), .yarn/cache is checked to see if there are any packages that would be marked for deletion. If the environment it's run in doesn't match the last (mutable) environment that yarn install was run on, then the packages that were added there will be marked for deletion, causing the --immutable-cache checks to fail. While technically correct behavior, this is a surprising result.

To reproduce

1. Starting on a Mac, create or check out a Zero Install project that relies on packages that need to be built (e.g. rollup or esbuild)
2. Edit the .yarnrc.yml file to add supportedArchitectures.os.current and supportedArchitectures.os.linux
3. Run yarn install --immutable --immutable-cache and see that it runs cleanly
4. Check in and push your changes
5. On a Linux machine, check out the project
6. Run yarn install --immutable --immutable-cache

Expected result:
yarn install --immutable --immutable-cache runs cleanly

Actual result:
yarn install --immutable --immutable-cache fails with an error because the packages for the darwin architecture become marked for deletion

Environment

System:
    OS: macOS 14.6.1
    CPU: (12) arm64 Apple M2 Pro
  Binaries:
    Node: 20.14.0 - /private/var/folders/xn/vw4zf9652s12bf3rlv1dv2jc0000gn/T/xfs-a202132a/node
    Yarn: 4.4.1 - /private/var/folders/xn/vw4zf9652s12bf3rlv1dv2jc0000gn/T/xfs-a202132a/yarn
    npm: 10.7.0 - ~/.local/state/fnm_multishells/15134_1725055459573/bin/npm

---
I don't have easy access to the Linux-based buildpack instance that I discovered this bug on, but I think it's safe to assume that this bug will present itself whenever "current" is not also listed in the relevant `supportedArchitectures` entry

Additional context

Workaround:
Do not use current anywhere inside of supportedArchitectures, and instead explicitly list all supported architectures.
