Finally get rid of taggedSemanticVersion approach

Change next version calculator to act according to the next algorithm:
1. Calculate next version candidate based on the base one
2. Look for the latest `PreReleaseTag` matching Major, Minor and Patch
of the next version candidate.
3. Append the `PreReleaseTag`, if found, to the next version candidate.
4. Compare the next version candidate with `Context.CurrentCommitTaggedVersion`
including the `PreReleaseTag` comparison.
5. Increment the `PreReleaseTag` of the next version candidate if versions mismatch.
6. Return the next version candidate.
