Automated version counting

**Describe the problem you have/What new integration you would like**

When using the versioning property, all the numbers have to be entered manually.

**Please describe your use case for this integration and alternatives you've tried:**

Would it be possible to make the lowest version key self-increasing to show each compile? It must no represent the true number of compiles for the respective version.subversion, but just an increase of the last number to differentiate builds.

**Additional context**

Helpful and nice to have

The request concerns ESPHome's versioning property and asks for automatic incrementation of the lowest version component for each compile. Start by locating the versioning implementation and its build entry point; done means successive builds receive distinct incremented values without manual version-number entry.
