chore(deps): upgrade Go sdk to 1.23 (#6628)

Release notes: https://go.dev/blog/go1.23

Also upgrade hay-kot/scaffold so I can use some validator features in
the 'aspect init' template.

---

- Covered by existing test cases
- Manual testing:

built CLI, ran `init` against current HEAD template, prompts look good
and it creates working app
