STCOR-745 bump stylelint to v15, and co-deps too

Bump `stylelint` to `v15`, `stylelint-config-standard` to `v34`. The
community config standard has evolved quite a bit since we first
implemented this, necessitating turning off several warnings in
`.stylelintrc` in order for code as-is to pass; see STCOR-746 for the
details on removing these exceptions.
