[TASK] Upgrade to Lit v3

Lit v3 is a new major release and contains breaking changes, but they do
not affect us: It mainly drops IE11 support (which we already dropped)
and switches to ES2021 modules (which we already use as well):

npm install --save \

    lit-html@^3.0 \
    lit-element@^4.0 \
    @lit/reactive-element@^2.0
npm run build
