Fix deprecation validator message to require leading v (#180467)
Fixes https://github.com/flutter/flutter/issues/178246

This PR updates the deprecation validator error message to clarify that
the version must include a leading `v` (for example, `v1.2.3`).

It also updates the deprecation template documentation to match the
validator requirement.

No functional behavior is changed; this only improves clarity and
consistency between the validator and documentation.
