Bump XML::LibXML's $VERSION across every version-bearing file in one shot. Use whenever the user asks to bump, change, set, or promote the XML::LibXML version (e.g. "bump to 2.0212", "promote the dev release to stable", "cut 2.0212_01"). Wraps a Perl script that auto-detects the current version from LibXML.pm and rewrites every file carrying the `# VERSION TEMPLATE: DO NOT CHANGE` marker plus the `<edition>` tag in docs/libxml.dbk. Optionally renames the topmost Changes entry when promoting a CPAN-underscore developer release.
