Upgrade lint and dev tooling to latest majors

Bump eslint to ^10, @eslint/js to ^10, eslint-plugin-ember to ^13,
eslint-plugin-n to ^18, globals to ^17, stylelint to ^17,
stylelint-config-standard to ^40, sinon to ^22, and concurrently
to ^10.

Fix three new lint violations surfaced by the newer versions:
- Remove redundant padding-left after padding shorthand (stylelint 17)
- Remove useless null assignment before find() (eslint 10
  no-useless-assignment)
- Attach caught error as cause on rethrown Error (eslint 10
  preserve-caught-error)
