Install shared components during EW install (#31196) (#31208)

* fix: install shared components during EW install

* chore: ignore `@element-hq/web-shared-components` for knip

* chore: remove shared-components operation in layered.sh

EW `yarn install` is also installing shared-componenents dependencies.
`link:` in `package.json` works nearly like `yarn link`.

* Iterate
