[AXON-19] feat: nightly versioning & release scripts

[sdzh-atlassian]

What is this?

A set of scripts to define the versioning behavior for nightly releases, in line with the vscode docs

In this implementation:

• Versions with EVEN minor number (e.g. v3.0.14, v3.2.1) - are treated as stable
• Versions with ODD minor number (e.g. v1.1.1, v3.1.0) - are treated as pre-release (or nightly)
• Nightly versions increment patch independently - except when there's a next stable release, then the major/minor is bumped accordingly, and the patch is reset to 0
• Nightly versions are suffixed with -nightly to indicate pre-release as per semver

How was this tested

• Bunch of runs for the version scripts to simulate the different stable version updates
• Played around with these build scripts in a separate repo to satisfactory results
• Ran release pipeline once here - but more testing will follow once the CI code is merged to `main

As an afterthought - added a check to validate the version number and fail early - in case someone tags incorrectly by mistake
