Feat: Improve success messaging related to gh workflows and credentials

### Which areas does this feature request relate to

- [x] Create Plugin
- [ ] Sign Plugin
- [ ] Plugin E2E
- [ ] Plugin Meta Extractor
- [ ] Documentation

### Problem

When scaffolding a plugin we create github workflows to assist plugin devs build, release, check compatibility, and keep create-plugin up to date. For these github workflows to work properly the plugin developer needs to add secrets to their gh repo. This information isn't clear and could lead to devs being frustrated when some of these workflows first run.

### Solution

We should add information to the success message when a plugin is first scaffolded indicating which secrets need to be created or link to the relevant developer docs that explain the process.
