feat: add support for prereleases

[MichaMican]

closes #2

This pull request adds support for prerelease versioning to the semantic versioning GitHub Actions workflows. It introduces new workflow inputs for prerelease handling, updates the version calculation logic to distinguish between stable and prerelease tags, and ensures that release notes are generated from the correct base tag for both stable and prerelease releases.

Prerelease versioning support:

• Added is_prerelease and prerelease_name inputs to .github/workflows/semver-version.yml to allow generating prerelease versions (e.g., 1.2.3-rc.1) and specifying a custom prerelease identifier.
• Updated the version calculation logic to find both the last stable and last prerelease tags, increment the prerelease version appropriately, and build the correct version string for both stable and prerelease releases. [1] [2]

Release workflow improvements:

• Passed the new is_prerelease input to the release workflow and used it to conditionally add the --prerelease flag to the gh release create command. [1] [2] [3] [4]
• Ensured that release notes are generated starting from the correct base tag (previous_tag_for_changelog), whether releasing a stable or prerelease version. [1] [2] [3]

Version calculation and changelog generation:

• The workflow now outputs both the previous stable tag and the previous tag used for changelog generation, improving accuracy for release notes in both stable and prerelease scenarios. [1] [2]

These changes make the release process more flexible and robust, supporting both stable and prerelease workflows.
