Allow uppercase letters in pre-release version identifiers

[Copilot]

The version schema regex patterns only accepted lowercase letters [a-z] in pre-release identifiers, rejecting valid SemVer identifiers like RC, BETA, or Alpha. SemVer spec requires support for [0-9A-Za-z-].

Changes

• Updated regex patterns in version.schema.json to accept [a-zA-Z]:
  • version property pattern (line 34)
  • versionHeightOffsetAppliesTo property pattern (line 74)
  • gitCommitIdPrefix property pattern (line 97)
• Added test coverage for uppercase pre-release identifiers

Example

{
  "version": "2.3-RC1"      // now valid
}
{
  "version": "1.0-BETA"     // now valid
}
{
  "version": "2.0-Alpha.1"  // now valid
}

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• 3dovsblobprodeus2188.blob.core.windows.net
  • Triggering command: dotnet restore --no-dependencies /home/REDACTED/work/Nerdbank.GitVersioning/.codeql-scratch/dbs/csharp/working/32A0A2D38A721DD2A3E59F6279CF8961/missingpackages_workingdir --packages /home/REDACTED/work/Nerdbank.GitVersioning/.codeql-scratch/dbs/csharp/working/missingpackages /p:DisableImplicitNuGetFallbackFolder=true --verbosity normal --configfile /home/REDACTED/work/Nerdbank.GitVersioning/.codeql-scratch/dbs/csharp/working/nugetconfig/nuget.config --force (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

This section details on the original issue you should resolve

<issue_title>Version schema only allows lower case pre-release versions</issue_title>
<issue_description>Current version pattern in the version.schema.json allows only lower case pre-release version [\da-z\-] while the semver specification allows any case:

Identifiers MUST comprise only ASCII alphanumerics and hyphens [0-9A-Za-z-]</issue_description>

<agent_instructions>Expand the version schema to allow upper-case letters.</agent_instructions>

Comments on the Issue (you are @copilot in this section)

@AArnott I'd take a PR that fixes this. But as the current bug protects you from .NET SDK bugs, I agree with @KalleOlaviNiemitalo and am in no personal rush to fix this. @AArnott It looks like it is.
