Name the product "The Rightup" everywhere the recipe shows it

Problem/Motivation

The recipe writes the product name three different ways, The Right Up, The RightUp and a bare RightUp, across page copy, podcast transcripts, footer logo alt text, the README, the CHANGELOG, the CI comments, the testing-user scripts and the test step definitions.

The theme already calls itself Vartheme BS5 Rightup, and the Drupal CMS installer lists the template as The Rightup, so what a visitor reads does not match either.

Steps to reproduce

1. Install The Rightup site template.
2. Read the footer credit line, the FAQ and the newsletter heading on the home page.
3. Open the Podcasts page and any episode, then the About us and Advertise pages.
4. The product name appears as The Right Up, as The RightUp and as a bare RightUp.

Proposed resolution

One name everywhere: The Rightup. Viewer-facing copy only. Machine names (rightup, vartheme_bs5_rightup), file names and paths are untouched. A few sentences are reworded where the article does not fit, for example Every Right Up show, in one place becomes Every show from The Rightup, in one place.
