fix(composer): Make --minimal-config flag configurable

[elaman]

Changes

Currently --minimal-changes flag is being applied to composer commands. It was recently introduced in PR #34218. This has caused following issue #39823. As a solution, new composerMinimalChanges configuration is introduced, which allows --minimal-changes to be optionally applied instead of being a default behavior.
