chore(web-components): fix devDependencies

[samsiegart]

refs: #6064

If this package is used from npm (not a yarn link via agoric install), when I try to build the dapp I see errors from inside the package complaining that lit and @lit-labs/react can't be found. When I do yarn link @agoric/web-components the errors go away.

I haven't verified this fix (not sure how), but I think moving these to dependencies will make the dapp transitively download them.

And looks like it also causes an error in netlify deploy:

[vite]: Rollup failed to resolve import "@lit-labs/react" from "node_modules/@agoric/web-components/react.js".
