Implement when PreleaseLabel is empty, the PreleaseTag is generated correctly

BREAKING_CHANGES.md

@@ -27,6 +27,7 @@
 *   The process of increasing the version with bump message when `CommitMessageIncrementing` is enabled and increment strategy is `None` has been changed.
 *   A new configuration property with name `version-in-branch-pattern` has been introduced. This setting only applies on branches where the option `is-release-branch` is set to `true`. Please notice that the branch name needs to be defined after the version number by default (instead of `support/lts-2.0.0` please name the branch like `support/2.0.0-lts`).
 *   The `is-release-branch` property of the `hotfix` branch setting has been changed from `false` to `true`. If present the hotfix number will be considered now by default.
+*   In the git hub and the git flow workflow the `label` property is by default set to an empty string on the `main` branch. This yields to a pre-release version on `main` with an empty tag. Instead of for instance `1.0.1+46` git-version generates the full semantic version `1.0.1-46` instead. This behavior can be changed to generate only main versions (no pre-release version) with setting the label to `null` (Please keep in mind that the `label` property on root needs to be set to `null` as well otherwise the fallback applies). This change is caused by issue #2347.
