Unlocks the given dependencies.

Since this is a destructive action, unlocking dependencies only occurs when passing arguments/options:

• dep1 dep2 - the name of dependencies to be unlocked
• --all - unlocks all dependencies
• --filter - unlocks only deps matching the given name
• --unused - unlocks only unused dependencies (no longer mentioned in the mix.exs file)
• --check-unused - checks that the mix.lock file has no unused dependencies. This is useful in pre-commit hooks and CI scripts if you want to reject contributions with extra dependencies
