fix(site): open TemplateBuilder template docs in new tab (#26589)

Mainly makes the template builder's external docs/registry links behave
consistently.

Includes some small changes to make copy consistent (sentence casing for
links + period after page header subtitle, sourced from
[Figma](https://www.figma.com/design/z1qkNiNIya2myaVW4kR6jP/Template-creation-builder?node-id=257-906&m=dev))

Also, `noreferrer` has automatically been applied to `target="_blank"`
links in major browsers since 2021 ([source
