chore(deps): update eslint to 10.0.0

[MikeMcC399]

Supersedes several Renovate PRs

Situation

The repo currently uses the older eslint@9.39.2 release which enters end-of-life on 2026-08-06.

eslint@9.39.2 also reports a high severity ReDoS vulnerability GHSA-3ppc-4f35-3m26 that is resolved in eslint@10.0.0. This is only mentioned for completeness, as this type of vulnerability is not really relevant when carrying out internal linting of the repo where the files to be linted are under repo control.

Change

• Update to eslint@10.0.0
• Update other linting related dependencies to latest versions

Verification

On Ubuntu 24.04.4 LTS, Node.js 24.13.1, execute:

npm ci
npm run lint
npm run format:all:check

and confirm that no errors are reported.

Sure! There is still an unsolved vulnerability from eslint@10, because they're using ajv@6. First the maintainers of ESLint have to solve that one though because higher versions of ajv are not compatible with eslint.
