increment: inherit from incoming branch

[AurimasNav]

Detailed Description

Increment setting to "inherit" from incoming branch. I would like my main branch version increased, based on the settings of the branch being merged into it.

Context

I would like to rely on manual version bumping with +semver: minor as little as possible. If I have feature branch with configuration increment: Minor it would be nice that when I merge this branch into main it would inherit the Minor increment setting.

It's actually not clear for me what you trying to achieve with the feature. Could you please write an integration test and describe in it what you are expecting from this feature?

[Test]
public void __Just_A_Test__()
{
    string yaml = @"...";

    var configuration = ConfigSerializer.Read(new StringReader(yaml));

    using var fixture = new EmptyRepositoryFixture();

    fixture.MakeATaggedCommit("2.0.0");

    // ✅ succeeds as expected
    fixture.AssertFullSemver("2.0.0", configuration);

    // ❌ expected: ...
    fixture.AssertFullSemver("...", configuration);
}

This what you want is already possible in GitVersion with the usage of mainline mode:
