chore: remove deprecated dependabot reviewers and annotation fixes

[tomowatt]

Dependabot reviewers are being deprecated see - https://github.blog/changelog/2025-04-29-dependabot-reviewers-configuration-option-being-replaced-by-code-owners/ - and we already have CODEOWNERS set up so removing them to avoid further comments on PRs from Dependabot

And committing the 'docs' changes from make docs
