feat: support all SemVer 2.0 pre-release identifiers

Replace the RC-only pattern with a generic SemVer 2.0 pre-release
pattern so that tags like -alpha, -beta, -dev or -rc are all correctly
detected as pre-releases. Previously only -rc tags were recognized.

Also configure git user identity before tagging in the auto-release
workflow.

+## Pre-releases
+
+Tags containing a hyphen-separated pre-release identifier according to [SemVer 2.0](https://semver.org/) are treated as
+pre-releases (e.g. `v1.0.0-alpha`, `v1.0.0-beta.1`, `v2.0.0-rc.2`). When `new-tag` is a pre-release tag, the action:

+2. Skips changelog generation entirely.

+When auto-detecting tags (no explicit `old-tag`/`new-tag`), the action ignores pre-release tags and selects the two
+most recent stable tags instead.
