Build maturity identifier

The build maturity identifier is a label like alpha or beta that appears in pre-release version metadata.

For example:

1.2.3-beta.7658

1.2.3-beta.7658+feature-mybranch.6ab397d5

The build maturity is derived from the branch name using a regular express set in the MSBuild property Git2SemVer_BranchMaturityPattern. See MSBuild properties.

The default settings are (first match from top is used):
