🚀[Feature] Specify configuration using a config file

[Marius Storhaug (MariusStorhaug)]

• Fixes Add a settings file to contain config #4, by introducing a new parameter ConfigurationFile which takes the path to the config file in the calling repo.

Bug fixes:

• Fixes an issue that would fail when creating the 11th incremental prerelease. Sorting was done on tagName. This cause the sorting to not sort *.10 at the end, leaving *.9 as the last prerelease, and trying to publish a *.10 again. Changed to sorting on the incremental number of the tag name.
• Fixes an issue that would create a prerelease even when a PR gets closed, leaving the latest prerelease in place after automatic cleanup.
