-Renovate's 'Same Major' versioning is specifically designed to address scenarios where version specifications, denoted as X.Y.Z, signify a range of compatibility from greater than or equal to X.Y.Z to less than X+1.Y.Z. In essence, each individual version is to be treated as a constraint.

-This method is handy when managing dependencies like dotnet-sdk's rollForward settings. Let's say a project uses dotnet-sdk version 3.1.0. It needs to be compatible with any version in the 3.x.x range but not with versions in the next major version, like 4.x.x.

-This process employs Semver-Coerced versioning beneath the surface, wherein single versions (e.g., `X.Y.Z`) are converted to a range like
-`X+1.0.0` and then passed to the corresponding semver-coerced method.
