1 check is failing because the Nuke website is down. |

Nuke is abandoned now and the website is unlikely to come back online.

Throws if environment variable is not found and has no fallback. This is deliberate to stay consistent with other usages of environment variables, for example in assembly file version.

Description
Supports environment variable substitution in the label configuration for a branch using the established format used elsewhere. Fallbacks are also supported if the environment variable is not found. The changes are backwards compatible and should not fail for existing configuration.
Documentation detailing the changes has been added to
configuration.md.Related Issue
Resolves #4745
Motivation and Context
Allow labels to include environment variables as well as regex-captured variables. This is useful for CICD environments like GitHub where the pull request head_ref can be provided instead of the merge commit target.
How Has This Been Tested?
Unit tests covering the new functionality have been added.
