ci: special case tooling-cli-shared-api review group (#37467)

The new tooling-cli-shared-api is used to guard changes to packages/compiler-cli/src/tooling.ts
which is a private API sharing channel between Angular FW and CLI.

Changes to this file should be rare and explicitly approved by at least two members
of the CLI team.
