Fix maven pre-deploy snapshot version validation: require SemVer-SHA

[dmitrii-ubskii]

What is the goal of this PR?

Fix regression introduced in #397: prepending 0.0.0- to the commit SHA for snapshot assembly broke the validation in the deployment script, which expects either bare SHA or any string ending with -SNAPSHOT. We now require either a major.minor.patch version with the SHA at the end, or any string ending with -SNAPSHOT.

Trivial Change

• This change is trivial and does not require a code or architecture review.

Code

• Packages, classes, and methods have a single domain of responsibility.
• Packages, classes, and methods are grouped into cohesive and consistent domain model.
• The code is canonical and the minimum required to achieve the goal.
• Modules, libraries, and APIs are easy to use, robust (foolproof and not errorprone), and tested.
• Logic and naming has clear narrative that communicates the accurate intent and responsibility of each module (e.g. method, class, etc.).
• The code is algorithmically efficient and scalable for the whole application.

Architecture

• Any required refactoring is completed, and the architecture does not introduce technical debt incidentally.
• Any required build and release automations are updated and/or implemented.
• Any new components follows a consistent style with respect to the pre-existing codebase.
• The architecture intuitively reflects the application domain, and is easy to understand.
• The architecture has a well-defined hierarchy of encapsulated components.
• The architecture is extensible and scalable.
