All docs examples share the same `node_modules/` (symlinked into each
example from `aio/tools/examples/shared/node_modules/`). However, each
example type has a different `package.json`, which comes from
`aio/tools/examples/shared/boilerplate/*`). In order to ensure that the
dependencies in each example's `package.json` are the same as the ones
in the symlinked `node_modules/` (i.e. the ones that CI tests are run
with), we have a script (`yarn run sync-deps`) that can sync
dependencies from `shared/package.json` into the boilerplate
`package.json` files.
Previously, this script had to be run manually, which was easy to
forget/not know about and resulted in the boilerplate dependencies
often being out-of-sync with the ones in `shared/package.json` (and by
extension, the ones that were actually installed in `node_modules/`).
This commit helps keep the boilerplate dependencies up-to-date in the
following ways:
- Adds the `sync-deps` script to the `postinstall` scripts.
This ensures that dependencies remain in sync whenever someone
manually updates dependencies in `shared/package.json`.
- Runs the `sync-deps` script as a Renovate post-upgrade task.
This ensures that the depenencies remain in sync whenever Renovate
updates dependencies in `shared/package.json`.
For more info on configuring post-upgrade tasks in Renovate, see:

- [allowedPostUpgradeCommands][2]
- [allowPostUpgradeCommandTemplating][3]
NOTE:
For the Renovate change to take effect, the [global config][4] in
`angular/dev-infra` also needs to be updated. This will be done in a
separate PR.

PR Close#47009
Previously, when updating the dependency versions in
`aio/tools/examples/shared/package.json` (which contains all
dependencies used in docs examples projects), one had to manually go
through all boilerplate directories and update the `package.json` files
with the same versions.
This commit simplifies this task by automating it via a Node.js script.
