chore: upgrade lerna to ^8.2.3 and update configuration format

Update lerna from version 6 to 8.2.3 across the repository and modernize
lerna.json configuration to match Lerna 8.x schema.

Changes:
- Upgrade lerna dependency to ^8.2.3 in root and workspace boilerplate
- Update lerna.json to Lerna 8.x format:
  * Add $schema reference for editor validation
  * Remove deprecated "lerna" and "useWorkspaces" fields
  * Move conventionalCommits under command.publish
  * Keep existing npmClient, npmClientArgs, and registry settings
- Update generated workspace template to use new lerna.json format

Files modified:
- package.json (root)
- lerna.json (root)
- boilerplates/workspace/package.json
- boilerplates/workspace/lerna.json
- packages/templatizer/src/generated/workspace.ts
