chore(dependabot): refresh dependency update configuration (#7561)

# Description of Changes

- Added `/testing/compose/mcp-client-check` to the existing Docker
Compose dependency monitoring configuration so dependencies used by the
MCP client check environment are covered by Dependabot.
- Added a `tanstack` dependency group matching `@tanstack/*` packages,
allowing related TanStack updates to be reviewed together.
- Added a `typescript` dependency group covering both `typescript` and
`@typescript/*` packages.
- Removed the obsolete `pip` Dependabot configuration for
`/testing/cucumber`, as dependency management for this area has moved to
the current `uv`-based setup.
- Kept the existing Dependabot scheduling, cooldown, grouping, and
rebase strategy conventions unchanged where applicable.
