Create a github action to update transitive dependencies of tsp-client

We have added `package-lock.json` and `package.json` to `eng/common` folder to pin the version of `tsp-client` used in SDK language repos.

We also have configured `dependabot` to update version of `tsp-client` in these two files.

Additionally, we will need to run `npm update` regularly to bump the transitive dependency of `tsp-client`. The plan is to create a github action for it.

Start by inspecting eng/common/package.json and eng/common/package-lock.json to understand the pinned tsp-client dependency and the npm update command that must run. Create a GitHub Action that regularly updates the transitive dependencies there; done means the workflow runs successfully and produces the expected dependency changes.
