chore(deps): bump @rancher/shell to 3.0.13 (#1130)

Clears 26 of the 54 open Dependabot alerts (axios, dompurify, serve-static, and
drops vulnerable send / @tootallnate/once copies).

3.0.13 ships the flat-config ESLint 10 toolchain, so lint now routes through the
@rancher/shell launcher (keeping the legacy .eslintrc on ESLint 7); a prelint step
installs an ESLint-7-compatible eslint-plugin-jest into the isolated toolchain.
