[Request]: Support Swift Crypto v4

[fpseverino]

Feature or enhancement request details

I'm working on a project that uses both Containerization and another package that requires Swift Crypto v4.
Containerization currently requires Swift Crypto v3, so SPM fails to resolve the dependencies.
However, I think Containerization could easily support a wider range of Swift Crypto versions, including v3 and v4, as described in the Swift Crypto README.

@fpseverino Do you want to create a PR that defines the range as "3.0.0"..<"5.0.0" (without changing Package.resolved, we'll do dependency updates routinely as part of upkeep)?

The README indicates that the breaking changes are minor and won't affect most users. I'm seeing no problems building the project with the v4 library as well.

@jglogan Just opened the PR! Locally on my machine I updated the dependencies and run the tests, everything should be fine
