Treat additional labels in priority scoring of issues

[antonkovalenko]

Action in https://github.com/ydb-platform/ydb-embedded-ui/blob/main/.github/workflows/priority-score.yml

Calculates CalculatedPriority parameter for an issue based on labels.

finalScore is calculated as follows:

finalScore = Math.round((defaultReach * defaultImpact) / defaultEffort);

For issues that labeled with label "heart xeno" i want to add as much value as defaultImpact does.
For issues that labeled with label "feedback" i want to add as much value as defaultReach does.
